(Solved) Key fob will start the car but won't unlock the car

[jrock]

Key fob will start the car but won't lock / unlock the car. I just replaced the fob battery and the problem still exits. Note: I have a VAGCOM, and I did cleared all of the fault codes in the “05-Acc/Start Auth.” Section. Not sure what the next step is.

do you have to hold the key up to the steering column to start? or just have the key in the car to start like normal?

What codes were stored?

did they come back?

The car starts like normal, no need to hold the key up to the steering column to start. Here is the code.

I got it after a few tries with this method...

Remote Control Programming (1997 ON)
Procedure
1. Switch Ignition ON and leave the key in the ignition.
2. Mechanically lock the vehicle using the Drivers door using a second
key.
3. Using the remote control press the Unlock button once, and the horn
will sound once.
4. Wait 6 seconds and press the unlock button once to activate the coding
procedure. The remote control will now be programmed.
NOTE : When performing programming on additional remotes the procedure
is the same, except you press the unlock button 2, 3 or 4 times for the
different remote.
For example : If programming 2 remotes press the unlock button twice with
a 1 second interval between each press, repeat for 3 and 4 remotes.
5. Switch Ignition OFF.
6. Remove key from ignition and check for operation.
7. The coding procedure can be repeated up to 4 times for additional remotes.
8. The ignition must be switched OFF between programming each remote
control.
Remote Control Erasing (1997 ON)
Procedure
1. Switch Ignition ON and leave the key in the ignition.
2. Mechanically lock the vehicle using the Drivers door using a second
key.
3. Press the remote control unlock button 5 times in 1 second intervals.
A short horn will sound.
4. Wait 6 seconds and press the unlock button once to activate memory
erase.
5. Switch ignition OFF, all remotes are now erased.
