Auto Locking doors
 

Now before you say search, I have and only one person mentioned something close to what I did. So,...

My X5 has always auto locked after a certain speed, which is irrelevant. I like this function and I am sed to it.
I have two keys, but only one seems to have battery power to operate remotely. I read the fix on the forums here and I put a new battery in but it still does not operate remote signals. It will start, unlock and lock ok as well as drive. My regular key is fully functional, all remote works fine.


I decided to see if maybe using the other key would put some life into it and used it for about five days, but had to manually lock and unlock the car each time I parked. I got tired of this and returned to using my remote keys. I am not sure, but I may have left the car unlocked from one key and locked it by remote from the other or it could have been locked and I locked it again by remote to be sure. I cannot remember as I have the attention span of a goldfish when it comes to menial daily tasks these days.


So now when I use my main key, I do not get the auto lock function and we still get these crazies washing your windscreens at the stoplights and than wanting money. I cannot figure what I may have done that caused this issue, but I have read in posts that you shouldn't press the fob buttons too many times near the car or in quick succession and during my search I was sure it was "WPoll", who asked one of the members if he had used a different key when his auto lock feature was disengaged?


So, does anyone have any ideas what might be the issue as this function was working 100% on the fully re,ote operating key, but stopped working after I used the key without remote function?

Have you tried to reinitialize the keys? If everything works with one key, it's probably a sync issue. Mine has three keys. Two are locksmith made. One of those started to act up. Not unlocking the doors. After a reinitialization, all the keys work properly.

Thank you for the reply, as youare talking to a BMW noobon the learning curve, re iniialise the key is not in my dusty ol brainbox yet.



How would I accomplish this BMW trickery, if you don't mnd pasing on the secrets?


Thank you, Jeff

Not sure it's whats causing your issue, but have to resync the keys after you change the battery

The following works for me, with my USA 3.0i.
Some hints:
key number 1, etc. (why would that matter?) - the number (order in which you do the programming) determines how some of the other memory things are done - e.g., seat adjustment memory. Maybe other settings such as door locking are also remembered separately by key #1, etc. (guess on that one). And that is the only reason for the bolded warning at the end, "Always initialize the keys in the same order."

The KL-R key position is what I consider the ACC, or accessory position, in between OFF and ON.

The point here is... only one key has a working remote function. There doesn't seem to be any point in initialising the one key that already works. :rolleyes:

It does sound like the key memory function has a role to play in this and I DID find this line of info.: -

2.1 Key Memory - Central locking system Automatic lock after pulling away

• active
• not active

The vehicle is automatically locked when it pulls away. It is still possible to open it from the inside. This function is effective when the doors are opened using the remote control.

So it seems the auto-lock function is only active if the car was unlocked using the remote (not manually).

This document covers what the various memory functions cover: -

Yes, automatic locking is one of the functions of Car & Key memory. When the vehicle is unlocked with that remote the settings are done accordingly. So for example seat memory settings and auto locking are done. So for the functions to work the remote has to be initialised with body module. But it still is a strange one if the previous key still has the sync with body module and remote locking is working normally but the individual key functions are lost. It could be that the coding options have somehow been erased and gone to factory settings. If this is the case it can be coded again with NCS.

Ok, that might get the other key working. Thank you for that.

Thanks Wayne, that list is handy. All the answers are great, but none really explain how I can get back the auto lock after moving off.

The reset of the other key now makes sense after changing the battery. No wonder it still doesn't work. :rofl:


I just cannot figure out how I had auto-lock one minute then used the other key, returned back to my working remote and auto-lock is now not working?

Is it worth me getting software and a OBDII to USB cable, just so I can access these functions.

As I do not have the original radio, I cannot make changes to the clock on the dash either, can this also be set up using one of these software people talk about when connected to a laptop?


Jeff

T everyone else, I thank you for your input, with all of you helping this forum is a great place. Cheers:guinness:

Cannot really explain, sometimes i lock/unlock the car with the plastic key when going to the beach, but then when start driving the doors still auto lock each time.
