Found it! (51 26 9 404 439) Standard installation time: 10 hours. | | | 08-17-2013, 10:54 PM | #4 | Senior Member Join Date: Nov 2004 Location: Bremerhaven, Germany Posts: 977 | Hmmm. The compilers of the ETK seem convinced that your car has central locking. | | | 08-17-2013, 11:36 PM | #5 | Junior Member Join Date: Aug 2013 Location: Edmonton, AB Posts: 6 | my car has no button for central locking i don't know why that is | | | 08-18-2013, 04:44 AM | #6 | Senior Member Join Date: Nov 2004 Location: Bremerhaven, Germany Posts: 977 | I probably should have asked a few questions earlier. What month and year was the car built? For which market (e.g., Canada, U.S., Europe)? What mods have been done to the car that touch the locks (e.g., an alarm)? If you lock or unlock a door or the rear hatch with a key, does the rest of the car lock or unlock as well? | | | 08-28-2014, 03:44 PM | #7 | Member Join Date: Oct 2007 Location: Los Angeles, CA Posts: 73 | Revive bump for this thread. I have a 95' 318ti base model that I'm completely restoring. Definitely an eye sore right now, but I've gotten most my m-tech interior in but wanted to wire in a central locking button in before finalizing the interior. Question is: Has there been a write up? I could tap into the stock alarm system but trying to go oem as possible if that makes any sense. | | | 08-28-2014, 04:48 PM | #8 | Senior Member Join Date: Nov 2004 Location: Bremerhaven, Germany Posts: 977 | Have you tried applying 12V through, say, a 1–2.2K resistor to pin 19 of the 26-pin yellow connector X13253 of the ZKE? If that doesn't work, you may need a later ZKE module, for 9/95 onward. | | | 08-28-2014, 07:27 PM | #9 | Member Join Date: Oct 2007 Location: Los Angeles, CA Posts: 73 | I've read through the etm manual. My car should have a zke module. If it will respond to the 12v signal is the question. If its just one signal wire that engages and disengages the locks then really its a lot simpler than I previously thought. Thanks. | | | 08-28-2014, 07:52 PM | #10 | Senior Member Join Date: Nov 2004 Location: Bremerhaven, Germany Posts: 977 | You are welcome. How easy the mod will be depends on when BMW added support for a central locking switch to the ZKE's hardware and firmware. I reckon you could retrofit a switch to an old ZKE that doesn't support it – with a couple small signal relays (one that magnetically latches) and some diodes, resistors and capacitors. I have done part of the mod in one car and the rest of the mod in another, but not yet the entire mod within a single car. Last edited by John Firestone; 08-29-2014 at 04:45 PM.
