Hey all! Need some help with a new gem unit on our '02 5door festa! Our car didn't come with remote central locking or an alarm and the misses would like remote locking, so looked into it and saw that we needed a different gem unit. We got a remote key for it aswell and Went and got what we thought would be the right unit from a scrappie, fitted it yesterday, fantastic, all worked straight after i fitted it! Done the learning mode, programmed the remote key, everything unlocked and locked, all the electrics worked, hazards, aircon, elec windows, rear boot release, everything! Misses got up this morning to go to work, remote didn't work so she unlocked the car with the key, as soon as she opened the door the hazards started to flash and didn't stop until i got back from dropping her to work and disconnected the battery! It's like the, non existent, alarm was going off without the noise! The car still starts and drives, but the remote fob didn't work, the hazards keep flashing. Any suggestions?

Here's our original gem off the car

Cheers people!
