nice!
so yeah you want to log in and go int the central locking module
open up block 003, this should get you to the screen where it shows you how many keys are coded in (2nd field) and the last field will show you when buttons on the remote are being pressed (the 0 will change to a 1 if it's registering)
This is where proceeded like so
- working key in ignition (window wound down just in case), and turn car on but not engine start
- go outside and
lock the car via the boot
- head back over to the driver's side so i can see the screen
TO START FRESH (delete all coded remotes) - if you want to add remotes just skip to the next bit
– On remote unit, press “Open” button 5 times in one-second intervals.
A short horn signal will sound (on mine the blinkers would flash and on VCDS field 4 would change with a "1" with each button press. I didn't get a horn sound)
– Then
WAIT 6 seconds, press “Open” button once to activate
(This is where i got the horn sound)
Memory is now erased, and the central locking system can no longer be operated by the remote unit.
Data in field 2 should read 0000
– Switch ignition off.
As many as 4 new remote units can now be coded
Coding remotes for central locking/remote window up or down
– Switch ignition on; leave key in ignition.
– Go outside and
lock the car via the boot
– Head over to where you can see the screen
– On remote unit, press “Open” button once. A short horn signal will sound (again, i only had blinkers and field 4 indicate the button presses being registered.)
Note:
– The “Open” button is pressed once for programming the first / a single, remote
– When programming additional remote units for the second, third or fourth memory addresses, press the “Open” button two,
three or four times, in one-second intervals (blinkers will confirm the presses are registered.)
– Example: press the “Open” button once, wait 1 second, then press once again to program the second remote unit.
–
After 6 seconds, press “Open” button once to activate the coding process.
The remote unit will now be coded, and it can be used to unlock the central locking system.
– Field 2 should now read "0001" indicating that remote is in position 1
– Switch ignition off.
– Repeat process for the additional keys
Note:
The key must be removed from ignition before the remote unit can be used to lock the vehicle.
The coding process can be repeated up to 4 times for additional remote units. In between each remote unit coding, the ignition must be switched off.
I really don't understand why this method didn't work for me when locking with the front door as per ALL other guides online but i've tried on both cars and erased then recoded all keys just to test the theory and it worked for me both times.
