Alarm ECU Replacement

Howdy,

I've searched High and Lo and can't seem to find a definitive answer, hopefully someone can gimmie a hand...

I have a 1994 M reg 300TDi Discovery, It was bought without any remote key fobs and with what are clearly replacement keys for the drivers door, which only work in the drivers door.

Recently the drivers door lock started to get stiff to lock, I took the door card off and loosened everything up and it was fine back to locking how it should... However this afternoon I came to lock the drivers door and something went clink and now the key just freely moves in the lock.

I removed the door card again and it appears that part STC1219 has snapped (I do have quite a handy vid if anybody would like to see it) so I'm currently now locking the car through the central locking on the inside from the passenger side and then locking the passenger door with the ignition key.

Now a new replacement STC1219 seems to be about £20 I haven't got time to go scrap-hunting at the moment and I'm working away from home...

I have found on fleabay however a "working" Alarm ecu, replacement door lock with original key and original "working" key fob and ignition barrel for £30

Is it possible to simply replace the alarm ecu? I don't want to remove the alarm just replace it so the key fob would work and trigger the central locking...

Cheers for reading!

Why do u wish to replace the alarm ecu? as all u need is a single button fob, which is DIY programmable, and u will have remote locking. The just repair or replace the drivers door lock.
Replacing the ecu is just unplug, undo the fixings and remove.

Howdy,

Thanks for replying!

It was merely that the cost of the keyfob plus that of the lock would equal if not be more then that of what I found on ebay, and if the ecu is essentially just plug and play it seemed quite a simple solution

Ok just purchase the kit u have found and just keep the ecu as a spare, u don't need it as u can still use your existing ecu.

I have a 2 button fob on mine, so is easier to replace the whole unit, which i did, but as above, there is no need on a single button system, the fobs are DIY programmable, so no need to buy more than you need, which is essentially nothing if you have an unprogrammed fob
