My suggestion to you is check BMW VIN decode to find out if you have CA package first. so I'm not sure why you have a fob that does not have a removable battery. Would I need to go to a stealership and get a comfort access key, or is there another alternative?įrom my understanding, if you have the ridges on your door knob you have comfort access but most people who have comfort access like my self, have replaceable battery door on the fob. The car only came with one key and does not seem to have a removable battery. My e92 has the ridges on the door handle indicating that I have comfort access (I just bought the car from an auction). After key identifies itself, CAS allows car to be opened by pulling on handle. When CA key is detected to be close to car, car asks CA key to identify itself. Key in trunk does not allow trunk to be closed and locked, preventing accidental key left in trunk.Grasp handle to unlock, press ridges to lock.Key in trunk allows trunk to be closed, accidentally locking in the key in trunkĪbove are standard functions (without CA), below are CA functions.FOB in dash slot allows Start of engine.So a clue in detecting the fundamental reason for not properly function is: Your CAS module works, but your CA module appears to not detect the key. Try practising with a door you can open first so you get the feel of it.There is the CAS module (front left driver area) which controls normal lock/unlock via radio remote, then there is a CA module (right trunk near seatback) that detects the location of the CA key to provide Comfort Access functionality (no need to press buttons on FOB or insert key into dash slot). Lubricate the lot and keep using the door as I suspect it was seized by moiture or disuse and became stuck as the locking pin that you can feel delatch when you slowly open the door latch with either handle with the door open and using a finger to reset the latch each time. Maybe it also teaches the other jammed door what you want it to do? these cars are getting old and probably imprinting on the owners mentality, so be nice to it ) Try practising with a door you can open first so you get the feel of it. You cannot put it back in the hole in the door metal unless you take it apart as the two parts and put the base in before the cover. At first I levered out the whole port hole cover but found I should have done it as a two step process. Make sure you pull out the inner oval like section on this port hole as it comes out and then if you want to you can pull out the outer part of the port hole. I sprayed al parts with WD40 and removdd the little opening cover next to the lock on the normally concealed door edge to access into the lock area. Then I used my finger to operate the door lock clasp instead of closing the door again, and opened and closed the mechnism with both door handles many times to ensure it was working. You can manipulate the inside and outside door handles while doing this trying to open the door.įinally it opened, no damage! I did scratch the window tint a liitle bit because i used a hacksaw blade but no big deal. After a while of doing this and feeling around with the tool. I used a hacksaw blade as a thin stiff insert between the window wound down and fully open and the inside rubber seal to get down to the locking mechanism at the rear of the outside door handle - thst is where you aim for, and then move the tool around feeling for a lever you can push down that is a mechanism that is springy and you can move. BUT then I found this and it worked for me. I read about making a hole in the door lining to break up the actuator and the risks with the air bag (DISCONNECT THE BATTERY FIRST AND LET THE CIRCUIT DISCHARGE FOR 15 MINUTES BEFORE MAUCKING ABOUT WITH THE EXPLOSIVE AIRBAG!!!), but was reluctant to do this but it seemed the way to go. I tried thumping against the inside and outside of the door to unjamb it. I tried multiple door handle operations inside and outside. I tried spraying WD40 or aerosol liquid lubrication into accesible areas. The lock indicator went up and down electrically/electronically via the actuator but the door would not open. the passenger door seixed and could not be opened by internal or external handle. I had this problem with our 528i E39 1996.
