Question on BMW 3-Series Alarm Install

hi, cheers for getting back to me wayne.... i have successfully installed my alarm, i left the old one where it was and fitted the new one with proximity and shock sensors, remote start, remote engine kill but im having a bugger of a time with the central locking. I have isolated the wires i need to splice into although i havent connected them, my central locking is not working at all, and didnt before i started the install. all doors must be manually locked with the key. my rear lights are working fine, i have checked the door switches and all work fine, basically im not suffering from the boot wiring harness problem, have you got any idea what the hell is wrong??? why wont my central locking work when everything else works fine??? the drivers door was the first to fail then the bootlid and passanger door failed a day or 2 later

No clue as to why the central alarm is not working - have you checked to make sure that the door sensors are correctly indicating that the door is shut? The system will not let you lock the doors on the car if it thinks one of the doors is open. These switches fail all the time (see the doors article for more info), and I think that may be your problem. If that isn't the case and you can still lock all the doors electronically by turning the key, then you can simply hotwire into the key-turn switch and use that to electronically lock all the doors. Not ideal, but it should work.
