[All] [Generic] Cobra 4138 Romote reprogramming?

[eltonbird]

I've got this alarm / immobiliser fitted, and last night my fob lost sync / broke and I can't find my spare. Had to be towed home until I could find my PIN and override procedure in the manual.

I've looked online but can't find any guides on how to re-sync a remote, so not sure if I'm stuck using the PIN, or can get hold and sync new fobs?

If anyone knows if this is possible and the procedure for doing so, would be a great help.

Thanks

Not sure if this will work as it is for a different model cobra but worth a try

6.1 - RADIO CONTROL BATTERY LOW
When the radio control battery becomes low, the radio control
LED will blink in an irregular way or once only instead of
remaining permanently ON until the button is released. Replace
the battery.
1. To change the battery, open the radio control as indicated
in the figure, levering in the zone marked “OPEN”.
2. Remove the battery as indicated.
3. Wait for 10 seconds.
4. Open the pack with the new battery. Only touch it on its
sides.
Insert the new battery, remembering to comply with the
polarity indications (+sign upwards, as shown in the figure).
5. Close the radio control and press button 'A' twice to check
the correct operation of the system.
Do this operation standing close to the vehicle engine
compartment.
6. Dispose the old battery in the special container.
6.2 - RE-SYNCHRONIZE THE RADIO CONTROLS
If the remote control battery is not flat, but the radio control
doesn’t work, proceed as follows staying as close as possible
to the vehicle.
A) Press both buttons on the radio control until the LED goes
OUT. Release them.
(The LED will come ON permanently).
B) Press button 'A' of the radio control standing by the engine
compartment the LED will flash. The re-synchronisation
procedure has been completed.
C) Press button 'A' of the radio control again to verify the
correct operation of the system

Do you have the touch keys with this model alarm?? If you do then you can program new fobs in but all have to be done at the same time. If the alarm should have a touch key and you don't have it then you won't be able to program any other fobs
