A dead key fob will a BMW start?
You won’t be able to use keyless entry or remote unlocking if your BMW has Comfort Access if the battery in your key fob has died. You can still enter and manually start your automobile, though.
Press and hold the key release button at the remote fob’s base while unlocking the door of your car, then slide out the internal key blade. This can be used in place of a standard key to unlock your car. You can locate a little hole on the bottom of the handle if the keyhole is hidden on your car door. Use the key blade to pry off the trim panel and expose the keyhole by inserting it into the hole.
Once you’re inside, put your remote key fob in the ignition slot or, if your car doesn’t have one, press it up against the steering column’s key markings. If your key fob dies, you will still be able to start your BMW using the start/stop button on the dashboard.
Even if your E90 doesn’t have comfort access, there is a way to start the engine and start driving without a key. A BMW anti-hijack feature, that is. Simply put the key in the ignition and start the vehicle as usual. Once you’ve finished, turn off the engine and take the key out of the ignition. Pushing the start button now without a key will start the automobile in roughly 10 seconds, allowing you to take off. Although many of you may already be aware of this feature, I figured I should still share it with those who don’t realize that their BMW has it.
It’s more of a safety feature than anti-hijack. The automobile will still start if you have a key issue and stall out on the railroad lines, allowing you to get off the rails.
done this previously. After considering the potential consequences, I decided to stop using the “DIY comfort access” method. hehe. however, thank you for posting for others.
It works for both my 2007-1 series and 2008-3 series coupes, however if you open the driver-door or wait a little bit longer before restarting the engine, this option is disabled. I tested this about a month ago.
Since learning about it on this forum, I’ve been doing this for approximately a month. I haven’t had any problems with it, and yes, I also use it to warm up my car. No need to panic because the radio turns off after a few minutes, and in case you’re wondering, the car will still be running even if the key fob is distant from the vehicle. I put this to the test the other day when I visited Walgreens.
I do this to get my car warmed up. not necessarily to warm the engine up, but more to warm my seat and the cabin. It’s excellent if my car is parked on the street or somewhere else where you can’t leave the doors open while it warms up. (Or use the laser key to unlock the door)
I regularly engage in this. You don’t even need to hold the brake pedal down; just reapply it, press the start button, lock your doors, and dash into the store or back into your house. However, I suppose you have leftover heat if you are entering the store.
Yes, I’d rather to take a chance than have my valve train begin to tick because they aren’t getting lubricated during short trips when the car isn’t warmed up. I appreciate the guidance nonetheless.
SURPRISINGLY, not every recommendation made by businesses is in your best interests. They’re a business, so if they can convince you to ignore your automobile and end up having to pay for more extensive repairs later on, they win.
Not to bring up an old topic, but wouldn’t starting the car twice be necessary for those who use this method to warm it up? Since the initial cold start is the toughest on the engine, I believe it is best to let the car warm up at that time rather than turning it off and putting it through a second cold start. Any thoughts?

- Using pliers or a screwdriver, first take off your silicone cover. Something pointy might work better to provide leverage because of the tighter seal.
- Now take the chip out of the gadget. It looks like a black square or translucent tube.
- Put the chip on a piece of tape, then secure it to the lock.
- Start your key by using a broken or fresh key without the chip.
- If the car won’t start, move the tape and give it another shot.
- Once you’ve located a place where your chip will function, glue it in place.
- The transponder chip, which is constantly close to the ignition lock, allows any key replica to function.
The fact that you are breaking a layer of protection may be a drawback, but it is not a major issue because your car’s anti-theft systems continue to function as deterrents.
Interestingly, since interference results from two transponder chips being close to one another, it could occasionally even be a better security mechanism.
