sigma alarm
 

just bought a 54 plate blob only came with one key but wont open/lock doors set unset alarm using keypad at the moment
tried a new battery and reprogramming via key pad( I have the code)
nothing happens
can I buy just a fob or used key and programme it to set reset alarmetc and use my existing key to start the car or if I reprogramme the bought key will my second immobiliser be disabled in my existing key


thanks in advance geo

uk or jap? does the key fit the door and boot barrels or just the ignition?

sorry meant to say its uk and key fits everything just at the moment i have to enter the 4 digit code twice to start so was thinking if i got a used key removed the blade and just used it as a fob (after pairing with car using the keypad)saves entering the code everytime
