Changing Central Door Lock Actuator aka gun!

Hi everyone and i'm back with another practical mods or rather, addressing another common problemson Iswara. It's about central door lock actuator, or so called the gun!

Sorry but I think the gun fails quite often too...

Why is it called actuator or gun? This is because normally, a stock central lock actuator, sometimes alsocalled central lock solenoid, looks more like a boxy type of design, at least for Protons. For the originals,the central lock actuator should look something like this:

The central lock actuator shown above are the rear left and rear right actuator taken out from a separateday.

And here comes the third party central lock solenoids that claimed to "last longer", "providing highertorque", and yet they're that cheap! Accessories shop usually carries them at a surplus price when youask them to change your door central lock. And not just that, they'll again make you informed that you'llneed a "new mounting points" for your central lock, oh did I say that's how many charges in a rowalready?

Alright, speaking about the gun type, you'll first get your central lock actuator replaced to a third partyones, which, some screws that are supposed to be there on your door will be taken and left blank, lettingrain water flow into your door like none of his business; Followed by some additional installation charge,which normally is simply, randomly drill some holes on your car door which the accessories guy "thinkthat its not a problem to get your car door drilled and let it rust because its so cheap to replace a door!".

So thankfully enough, I insists originals on all times as that's HOW, WHY, WHEN, WHERE, WHAT, andTESTED. That's how much force it should've needed to pull down or push up the door knob; That's whythe central locking mechanism is designed in this manner to minimize wear and tear to your door hinges;That's where the central lock actuator should be, the mounting points also holds together which creates

strength for the locking mechanism and hinges; That's when you should replacing your actuator as itwon't bulge anymore, rather then getting randomly stucked; That's what the mounting points are, tunedor matched to just that much the door locking sound should be; And that's the PROVEN and TESTEDdesign by the engineers! (Or you mean the bangla that simply drill hole on your car is an engineer too?Well... They'll probably tell you it won't rust your door too.)

So thankfully I insisted on the original boxy type or it is just me. Problem now is the passenger dooractuator seemed to quit as it sometimes doesn't lock or doesn't unlock, making the driver to manually lockand unlock manually when the actuator feels bad on that particular day.

So here comes the disassembly guide for the door panel.

STEP 1:First remove the red screws from the panels. If they're covered, get the flap off and unscrew it. You willalso need to remove the triangle protective plastic cover on the side mirror adjuster to get the panel out.

After that, the green boxes labels all the clips behind the panels. You'll like to pop them up. Pop one andothers will be easy for you.

After popping up all the clips, the purple area is just holder by gravity and "hook" from panel. Simply liftthe panel reversing the gravity direction and it'll come out smoothly. Get ready to balance the panel andfind a place to put where you won't get scratches on your panel. Accessories guy, nah they'll just rest iton the wall and there goes your panel trim scratches, whole line of it on the most obvious place. If youplace it with the "window fabric liner" against the wall, nah get ready for your tinted film to scratch, can bevery deep until you'll replace a new film.

Tips: If you need to rest it, rest it on a wall or something height of pail, so you don't get the window lineron the wall. Get some newspaper on the floor and make sure no sands or stones to scratch the panel. Ifwanted to lay to wall on panel side, get some cloth to cover the panel so that leave no scratches. If youreally need to rest the "window fabric liner" against the wall, I suggest masking tape the whole linerbefore resting on wall as the stones or risk DEEP scratches from minor dirt from wall. (Imagine have atiny tiny tiny tiny sand/dust on the liner, and you lower down the window and up the window back,GONE! One whole line of DEEP scratch going diagonally across! I don't like it on my cheap tint and I betyou won't like it on your Huper or 3M though)

STEP 2:Peel the weathershield off! Alright just peel off the left side. Basically lower left and upper left. I don't peelall the way as the "gummy gooey" seal will get less and less sticky, and eventually your weathershielddoesn't bond anymore due to dust, oil from fingers, age or the weathershield itself. Just peel "enough" toallow your workspace "not to be compromised", rather than "comfortable".

STEP 3:Identify the root cause of the problem by inspection. Start by locking and unlocking the door via centrallock system or alarm. Saw the green holder connected via a rod to a blue holder? That's the central lockmechanism, yea JUST ONE ROD. A weak central lock motor will not be able to "pull" and "push" thelock mechanism enough to make it lock or unlock. Basically it's just overcoming friction of the doorhinges, but at its position, you'll find out pretty much force is needed though. Basically central lock motordoesn't get damaged, it's just getting weak.

If you found your rod had misaligned, loosen or fell somewhere else, just replaced it back to its originalposition. Retest to ensure that solves the problem.

STEP 4:Here comes the cash part. My central lock motor is weak and guess its time for the 7 years old originalProton actuator to retire. Went to spare parts shop and they'll give you the gun type. Insists on box type,i'm not going to retrofit it with gun type, it's just too unnecessary.

After searching, they can't find the one for Iswara so they gave me a Wira one to fit. This will make mereuse back my old bracket as the bracket is entirely different from the Iswara's one. Note that all theactuators are shaped the same, the difference, if any, would be the inclining angle of the metal piececonnecting the motor and the rod. For rear, there is a difference between Iswara and Wira's one andmay need more modification to fit. This is due to the angle difference on the metal joining the motor andthe rod. So DO insists on Iswara's one as the Wira modification won't work well.

So here it is, original on the right and the Wira's new actuator on the left. The bracket is totally differentfrom the Iswara's one, a google search will bring you a result from another blog. It's a piece of oddlyshaped unbalanced design metal. Oh by the way I had checked out the parts at Proton Parts Centre, theoriginal part is OBSELETE! So just settle with anything or brand that spare part shops give you as longas the price sounds reasonable for you.

I then removed the mounting screws from the Wira actuator and test it. The strength of the new actuator

is just powerful.

I left it hanging like this while testing the new central lock actuator. The power during rotation can makethe actuator shake and not just vibrate!

So enough of testing and lets go to Step 5!

STEP 5:Now you'll like to remove the old central lock actuator from its place. The placement spot is very difficultto reach and to work with, and you have no access to any screws as well. So I resummon the pictureyou just looked at again because you blinked your eyes.

You will need to remove the 3 screws around the door latches, one above and two below. This will allowthe door latch to be "out of place" enough to install the actuator. Another screw, which is the only screwbelow the door latch, yes the grey one, will also need to be removed.

Next, remove all the linkages, no matter it is orange or green. You'll realized that the door latch andeverything seemed stuck in place even without all the mounting screws. That's how strong the linkagesare holding the latches and locks. Removing the linkages will allow you to free more movements that arerequired to replace the actuator.

STEP 6:Now I should resummon the last picture cause you didn't stare at it long enough.

You'll then realized that there are two vertically mounted screws beside the green holder and below theorange holder that holds the bracket within. The screws are screwed from within! What kind of design isthat? And how are you going to unscrew that? I was puzzled and concluded that to remove that, it willtake much more time and probably gonna take apart the whole door knob mechanism as well. As it'sgetting complicated, I recommend the following steps as an alternative.

Since the bracket loves to stay there, let it stay!

Move the bracket at a slight angle and you shall get enough space to unscrew the motor from behind.Unscrew two screws in this way!

Now you'll find there's one more remaining screw. And guess what, you just need to angle here andthere and you'll find the third screw positioned just nice in the glory hole below... That took me sometimeto figure out. Once you unscrew the third screw, the motor can be removed, catch the motor or it'll sendan audio shockwave through out your clumsy all metal car door.

So that saved all the hassle you'll need to take apart the bracket, you had just removed the old actuator!

STEP 7:Refit the new actuator by reversing back step 6. You can screw the actuator in any order you want. And

hey do remember the metal rod yea, take it out and placed it onto your new actuator! If you don't do itnow it'll be much difficult to do it later!

STEP 8:Align the door hinge. Hold it in place and start fixing all the linkages back into its original position. It's notdifficult to mess up the order or position as the linkages rods are rather fixed in position since they are outfrom factory.

STEP 9:

http://cyantjxian.blogspot.com/2014/09/changingcentraldoorlockactuatoraka.html 11/13

Reverse step 5. Test it now! Feel the power of the new actuator! (Or the power of your money well spentat least)

If your new motor is also weak, unable to lock or unlock properly, read further below after these steps.

STEP 10:Reverse back Step 3, Step 2 and Step 1. Inspect for any abnormalities, place back weathershield, andplace back the door panel. You're done!

Note for those coming from Gun type into Box type:If your car is modified into gun type and the bracket and screws are gone, congratulate your exowner oryour accessories men. You've made your life harder to reconvert into boxy type.

Boxy type central lock actuator is also much quieter and elegant when working. Boxy type actuator locksthe door lock more softly and due to its mounting and constructions with the door and bracket, sound isminimized a lot. The gun type is just making too much noise as its powerful, that bothered me, makingthe locking and unlocking feel like breaking something everytime.

Speaking about powerful, the gun types are normally mounted parallel to the door knob. Yes in theorythis gives the most powerful force to lock and unlock as its a direct drive, rather than rotational driveinstead. But sometimes I don't think I need that "powerful" force to lock or unlock. It's like punching thehinge down and sending the door knob flying during locking and unlocking. And that is further worsen bythe hinge design where locking and unlocking will strike a middle metal. Here comes the cheap lockingnoise and hopefully you didn't make any metal bent yet.

Now about the metal part, if the accessory installer drilled on your car door metal, you're going to have abad time, you'll suffer from rust on the car door panel, or the useless screws they used that catalyze therusting process. Please note that water does goes in to the area we're working here and rusting is prettymuch easy without any paint/coating on. That is why Proton had coated a layer of antirust in the doorand even weathershield it in first place! Try running your finger on the inner door panel metal, stickyright? Not mentioning the working noise is amplified by the thin door metal that's holding the gun.

My previous genius owner changed all four to gunlocking type. I spent sometime to reconvert them intothe originals ones. I'll now speak from my experience in converting the guntype into they box type for mycar:

In Step 5, you may not have the screw. Get the screw from spare parts shop or ask from you mechfriends for one piece to screw the actuator bracket. That's the important link that'll hold the bracket andthe actuator together. Nothing replaces that, you can't even reach to glue or weld the bracket if you wantto.

In Step 6, you don't have any screws! I replaced mine with cable ties instead, making it to loop togetherwith the bracket and the holes from the door hinge. You wanna make sure the cable ties are good andtight. If it's not tight enough, your actuator can't efficiently transfer the power to the lock rod as it willmove, and you'll pretty much peel your weathershield again very soon to readjust. If any of cable tiessnaps, not only it causes the the door lock and unlock to fail, you'll get annoying metal clunking soundwhen your car vibrates as the bracket comes into contact with another metal, that are supposed to befastened together.

One thing good about this step by using cable ties is it'll be unnecessary to unscrew the 3 screws on thedoor hinge. This is actually good as you can see the washer on the door hinge is pretty sharp to piercethe car paint into door body. This is to make sure the door hinge doesn't got loosened up overtime due tovibration and age, causing door randomly open or flew off during cruising. By using cable ties, the 3screws will stay with the car door forever and each time you replace the actuator would only need you tocut the cable ties off, not mentioning you can change the bracket for new one too!

Note for unable to lock or unlock even changed a new actuator:Get a new one from where youbought. But I think most slightly they will reject as you had, opened the packaging, and, OPENED THEPLASTIC BAG. But it's really their product fault! The actuator is so weak that it can't even push it inplace! Nope sorry but they normally won't admit it, they'll give some sort reason of your central lock relayweak and all sorts of reason even blaming you installed not properly or had spoiled it or blaming wiringproblem, for not exchanging it for you.

So I guess I can't get an exchange? Here's what you can do: (It's complicated, I took few days to finetune after installing) You'll need to get some metal rod in this process. Have a look at the picture below:

Reactions: funny (1) interesting (1) cool (1)

You'll need to get the metal rod (stick) and the link connector fastener (gold box with screws). Its sold atcar accessories shop or some car accessories shop in Jalan Pasar. First, you'll parallel the new metal rodwith your door knob pin metal rod. Then, you'll reach the new metal rod to the hook shaped metal rodfrom the boxy central lock actuator. Some adjustment will be needed on different lengths of theconnecting rod to enable the lock to lock and unlock properly. Once you've decided the length, proceedwith cable tie on the yellow circled part. This will hold the rods together properly. Link connector is notused as the boxy actuator will make rotations during lock and unlock, we do need some free play onrotations, but what we need the more lateral force from it. It'll take some time to adjust this and you'llneed to place the door panel back to reconfirm whether is it working properly as some rotational force is"convert" into lateral force through the door pin hole on the door panel. This will make the door unlock.Locking action will require much less adjustment.

Do ensure the "lock" and "unlock" operations are smooth. If there is jitter on joins, place more cable tiesto make sure the force doesn't split up in the intermediate yellow circled part. It's difficult to find abalanced lock and unlock position in this case. Always make sure the central lock actuator is morefavourable or bias to stay in "lock" rather than stay "unlocked". You'll rather manually unlocked your carthan locking it. Why? Imagine if the lock doesn't lock up properly and you had moved away from your car,thinking that arming your alarm had locked it well. And a grasp of door handle will pop the lock up if itsnot locked properly! The latch on door hinge has not traveled far enough to stay locked.

Alright, if this is not worth your time, I suggest getting another from another spare parts shop. Sometimesmaybe it's just manufacturing defect or sometimes the product may had been stored too long, stackedtogether and magnets repelled until its weaker than usual, not sure with that.

Hope these helps!
