New one? Key fob unlocks but doesn't lock.

Here's the sequence of events.

I have two keys, one I use all the time (1), the other (2) almost never.

The other night, very cold out, (1) wouldn't lock. I locked manually.

Later it worked fine again.

Next day I tried key 2. It unlocks fine, but won't lock. Tried it many times, same thing.

Anyone ever here of this?

Thanks,

jv

Well im glad to hear this has happened to someone else.

This has happened to me on numerous occasions over the last 6 months. Only difference is that the fob does not always unlock the vehicle.

Sometimes I can unlock the driver door but clicking the fob again does not unlock the other door. I end up having to press the unlock button on the dash or manually open the passenger doors by pulling on the interior handle.

Temperature does not seem to matter for me. Sometimes it's hot...sometimes it's cold.

Does not appear to be a battery issue as it will work fine for weeks on end after failing.

I think the first thing you should try is to re-program the fobs and see what that does. If that does not work, then we can just say it's a "button" issue and there's not much you can do but to get another key.

How do you reprogram the fobs?

Pretty simple.

Grab both keys, go inside the car.

1) Insert any key into the key hole and turn it to the 1 position (WITHOUT starting the car) and then turn it back to the zero position (as if you were turning the car off) within (I think) 5 seconds?. In reality this isn't difficult, just put the key in, turn it to 1, then to 0, then take the key off.

The next step must be done within 30 seconds.

2) Press and hold the UNLOCK BUTTON and then press the LOCK button (center button) three times. If done right you will see that the car will lock, and the unlock confirming the sequence. Put another way, you will need two hands. One will press and keep the unlock button pressed while the other one presses the lock button twice.

The important step is that you have to grab the OTHER key and do the same in step two within 30 seconds of programming the first key

This is so both keys get programmed with the same encryption... otherwise one key will end up having the new code but the other one won't.

So, to sum up:

Grab both keys; get in the car; start with one key; put it in; switch to 1, then 0; take key off; press and hold UNLOCK, and while holding unlock press LOCK three times; WAIT for confirmation of that key (car will lock, then unlock); upon confirmation; grab second key; and repeat to make sure both keys have the same code within 30 seconds.

I bought a new second key and was given the instructions as you mentioned except I was not told to do the second key within the 30 second. Now I have one key working with the remote key-less lock/unlock, but not both. Both keys will open the door with the insert and turn method, and both will start our X3, But I can only get one to work to lock/unlock with the buttons. What are my options to try to get both keys synced for remote lock/unlock?

Do the initialization process again.

Door actuator problems?

I happened to run into this over the past few weeks.. My key fob started to become intermittent then stopped working entirely, and after replacing the fob battery and going through the key initialisation the fob would unlock the car but not lock it.

The centre console lock and overhead lamp both work ok, and the car fuses checkout ok; then I noticed that the rear-view alarm indicator blinks fast after locking the car manually at the drivers door - not slow like it should - which means that either door wasn't closed properly or one of the lock actuators didn't close.

I *do* have a malfunctioning passenger door actuator. Sometimes it opens/closes normally and sometimes it doesn't operate at all, and after some experiments I can see that if I do a manual lock/unlock cycle with the key in the drivers door and my passenger door lock happens to work correctly a few times, then all of a sudden the key fob starts working normally again.

So basically it looks like one possible cause for the key fob failing to lock your doors is a malfunctioning lock actuator.

No Locking or unlocking from Keyfob

hiya my key fob is not locking or unlocking my 2006 x3 2.0D. i can use it manually and when locked the fuel filler is also locked. the interior light and foot well light both work as they should. I have tried to reprogram the keys many times and that does not work. i have taken the car on a 100 mile drive to recharge but that also does not work. The central locking switch in the dash works fine, locking all doors and trunk, as does unlocking/ Locking manually with the key in the door. Both keys have the same problem. Is it a fuse problem or is it the key battery. Any help would be appreciated.
