97 740iL - Alarm

I just came out to start up my 97 740iL which I hadn't driven in about a month. I hit the unlock button on my key/alarm and the alarm went off for about 30 seconds. I pressed all 3 buttons on the the key but to no avail. I unlocked the drivers side door manually. I tried to start the car but I get nothing at all. The car is completely dead. The P where the shifter is..the light next to it...is flashing. I can't lock the car back up. I live in an apartment complex. Obviously, nobody is going to steal the car, but I don't want kids to hop in the interior and mess things up. Does anybody know what just happened?

If you know how to UNLOCK your car when the battery is dead or low...then you have the same knowledge to LOCK your car under the same circumstance.

You insert the key into the driver's door lock cylinder and turn the key CLOCKWISE 90 degrees and the door should manually lock. Turn the key COUNTERCLOCKWISE 90 degrees and you can manually unlock the driver's door. You can obviously lock the other doors by pushing down on the door lock pins. You can do the same with the driver's door BUT it must be closed. The anti lock out feature prevents the driver's door from being manually locked when it's open.

It sounds like you need to find a way to keep your battery charged if the car is sitting for extended periods of being parked. When the battery voltage drops, the alarm siren may detect low voltage so it sounds off thinking someone is cutting power to the car in a theft attempt .

It was a dead battery!!! I charged it up and everything is fine now. Thanks for the help.

QSilver7, the car wouldn't lock manually with the key because of the battery being dead. I got a jump from someone and locked the driver side door up that way.

The whole purpose of being able to "manually" lock/unlock the car is that you DON'T need the battery. If your lock cylinders won't/don't turn to the manual positions...it's time to do some preventative maintenance on them and give them a little lubing so that the lock cylinders can fully articulate 180...and prevent you from being locked out of your car if there's an electrical power failure. Graphite or a product like Tri-Flow work great for lubricating locks. They don't leave oily residue that will attract a build up of dust/dirt/grime.

The locks on our cars are electrically actuated when the door lock cylinder is turned 45 to the left or right. Then there is the MANUAL actuation of the lock when the key is turned 90 to the far left or far right...the 90 position does NOT require the car's battery. This feature is designed so that the car CAN be locked/unlocked in the event of electrical failure.

From the owners manual and other BMW info:

Key in driver's door lock cylinder turned 90 counter clockwise to the manual UNLOCK position




{45 = electronic actuation of lock cylinder ||| 90 = manual actuation of lock cylinder}



Manual locking of trunk and trunk lock cylinder positions



{45 = electronic actuation of lock cylinder ||| 90 = manual actuation of lock cylinder}

Hmmmm. I don't get it. The key DID turn all the way in the drivers door. There was no response. The trunk worked just the way its supposed to.

I'll be driving the car a bit more often to keep the battery up to speed. The reason I don't drive it that much is because of a coolant leak. I think its the thermostat housing...a $1000 job. Not quite in the budget right now.

When manually unlocking or locking the door...there isn't a "response" in the sense like when there is electrical power. When the battery is dead (or low)...the physical movement of the door lock pin as you turn the key is the "response" you should get.

Again, there is no electronic actuation when the battery is dead and you're using the "MANUAL" unlock/lock procedure...you are physically locking/unlocking the door...which you can "feel" as you turn the key in either direction. If you stop turning before physically raising or lowering the door lock pin...then the door will remain in the state that it was in before you inserted the key into the lock cylinder. During an electrical failure...locking/unlocking your car is just as if your car didn't have an electronically actuated locking system....it's all physically actuated.

Just a quick tip while we're on dead battery gremlins....clean the battery terminals. I had a dead battery and when I pulled the cables the crud had isolated the juice from returning back to the battery.

I would suggest "eBay", Amazon.com, and a general internet search using a few key words (to find vendors that sell these things) since this is something totally aftermarket.

But why would you ask this question in a thread that is about something totally different? What' the connection between the car's alarm and dead batteries...and aftermarket sideview mirrors with lights in them?

If you need to ask a question that is about a different topic, you should click the NEW THREAD button on the e38 home page or within a thread that is discussing side view mirrors...that way it will be MUCH easier to find your post, as well as get responses from forum members that may know just where or how to answer your question. These members will not be looking in an "alarm" thread to answer a question about "illuminated side view mirrors"...these two topics don't have anything in common.
