Golf IV / Jetta IV :: 2002 - Key Fob Stopped Working / Door Or Trunk Not Opening
Nov 8, 2014
I was having battery issues and had a friend hook up a battery charger to my car today. They pulled some relays to see if they could figure out why it was starting right. When I left for work the car started fine but I notice my windows would not roll down at all. I figured no biggie I would deal with it tomorrow.
When I got to work I realized my key fob had stopped working too. Again, I have a key will unlock it after work and deal with it later. After work tonight, I go to the car, I tried the key fob and nothing. No surprise. But I unlocked the driver door and it won't open, try to unlock the trunk it won't open.
I was told they pulled the relays and reseated them when messing with the battery. I can see a red light flashing below the radio. To top it off the keys to my other car are locked in the trunk along with my purse!

Can I use my key to open my trunk in the case of a dead battery? I disconnected my battery last night to try it out, but it wouldn't open. Some people say turn the key 50 degrees, but I don't think my key will turn that far. I was also scared of snapping the key off in the lock.

I thought it was the trunk actuator, so I ordered a new one. I thought this because when I hit the button to open the trunk, I heard a slight buzz (not the sound of the actuator extending) but the arm didn't push out.
When I hooked up the new one to the wire to test it out the same thing happened. I also tested both actuators with a 9V battery and they worked correctly. So, it's not a problem with the actuator itself, and I don't think it's a problem with the wiring since there is at least enough power coming through to cause a buzzing noise...so I don't know what else it could be.

So I just got a 2002 1.8t, everything was fine until the fans and ac stopped working. After poking around the forums a bit I changed the following:
1. Fan Control Module. Result: nothing
2. Radiator Cooling Fan Switch Temperature Sensor. Result: nothing.
all fan components have the correct voltage going to them. Fuse 16 for the AC clutch is not blown and has power going to it. The AC compressor has power going to it. The fuses on the battery box have power going to them specifically S180.
My question is what am I missing? is it possible that the fans themselves could be bad? car is not overheating, the after run coolant pump kicks on. But the AC clutch is not spinning nor are the fans. btw AC clutch is not seized up.

I have a MK4 Jetta, I've owned it for about 1 year. I've never had a problem with the key, but in the last few days, it only opens the driver door? No matter how many times I hit the button it won't unlock the rest of the doors?

I have seen a few thread about this on many VW sites. People with doors that when you unlock doors don't open from outside until you open from inside or you have to give the door a slight push closed and then it will click and open with 1 pull of outside handle. The problem is the door latch/striker whatever you wanna call it that mounts to the car body itself. It needs to be adjusted up or down just a bit. My pass door would not open with first pull then I read somewhere about people pushing door and then pulling on handle for it to open. So I went and played with latch. Moved it up about 3/16" and door works perfect.

The following have stopped working (at the same time if I remember correctly): power door locks, power mirrors, power trunk release and rear defroster. We are also getting a tire pressure fault warning when the tire pressure is ok. As far as other items located on the drivers door, the power seat adjustment and power windows are still working. I checked every fuse in the interior box and the the rely ant fuses unde the hood. I exchanged the big, square, grey fuse for the rear defroster with the one for the starter and still no luck with that issue.

When opening driver side door, engine dies.Cannot access the convenience control module with VAGcom.
Swapped in another CCM, same behavior. Have not tried yet to access the swap module with VAGcom.
What might cause the 'engine kill' when door is opened? How to further troubleshoot?
Quick fix: disable 'door contact' (not sure, but assume it is integrated into the door lock/actuator (as a microswitch likely?).

As the title states, my alarm horn chirps when opening the unlocked passenger door in my '03 Golf. Asked the master tech about it and we sat there scratching our heads for a while. Nothing he's ever seen or heard before. What set of conditions would create this?

Recently,my 2003 Saturn Ion's electronic trunk opening buttons have stopped working ! A couple of times,I have found wiring casings underneath where we usually park the car at night and I even found what appeared to be a chewed up wire within the same spot. I've kind of checked for bad fuses. But, there is no listing for a fuse for the electronic trunk switches. Neither the button on the remote works nor the button inside the vehicle.

Mk IV Jetta. Central locking works fine. All other CCM functions are fine. Replaced CCM recently serial numbers match. When I hit the switch on the door nothing at all happens. When I use the key button the lights flash twice but no other activity. No broken wires between the body and the trunk lid. Actuator works when tested with a 9v battery.

I have a 2002 f150 supercrew, 4wd. The power door locks stopped working the other day and I am trying to fix it. So far I have checked the fuse in the power distribution box, good. I have checked the wires from the doors to the cab along the door sills to the rear doors , all good. I did find a couple of iffy grounds on the left kick panel and cleaned and repaired them. I am having a heck of a time finding the group of relays that control the lock and unlock functions. Remember , I have no power lock function at all. I would swear its not getting power to the relays but until I find them , I just don't know. Where they are supposed to be?

My entry pad on the outside of the drivers door stopped working on my 2002 Explorer. Not only does it not open the doors but they don't light up when push the buttons. I looked in the owners manuel for a fuse related to this but did not see one. Which fuse the number pad is controlled by?

Recently bought a 2010 Toyota Prius 1.8 and it was working very well. It used to display a message saying that the key battery is low. Then one day, the smart key stopped opening the door. After some reading on the forums, decided that the smart key battery might be really low, so used the mechanical key to get in and tried to start the car by placing the Toyota logo of the smart key on the power button. Since nothing happened, decided to replace the batteries anyways. After the replacement, tried again, but zip. The doors still won't unlock, and the proximity switch-on also is not working. Why? Is it an issue with the 12-v battery?

About 4 months ago I was at the gas station and when I tried opening my fuel door, the switch wasn't working. I went home, took the door trim off, and then removed the switch in order to clean it. Once I cleaned it, it worked but about every 3rd time that I clicked it. However, yesterday it finally gave out as I was at the gas station. So I came home and now I'm stuck because I don't want to break the fuel door.
I ran through the fuses in the fuse box but on the diagram none seem to be for the fuel door. The weird thing is that yesterday as the fuel door switch gave out, so did the interior door lock switch. Now I have to insert the key from the outside in order to enter the car. But the key cannot unlock the passenger door.
When I hit the interior door lock switch, I hear a click noise under the dash. I took a look under there and it seems to be a bunch of relays. It's very tough to tell which one is the one clicking.

My wife and I recently purchased an 02 Camry. Last night the drivers door stopped opening from the inside and outside. Then we noticed the window was getting stuck rolling down and when I pushed down a bit the door popped open! Happened a couple times before the window got stuck.

A couple months ago my Key Fob stopped working. I tried using the button and then tried to use the key to unlock the door. I'm trying to figure out if there is a possibility that the immobilizer in my fob is junk or maybe its something as easy as changing the battery (which is another issue in itself because I cant open the fob for the life of me) Once again just curious if there is something I can do to fix this issue without contacting and dealing with the dealership. Would like to be able to lock my car again at some point.
