It's more a function of how it is used, the link between the driver door lock cylinder and door lock actuator is designed weak to reduce theft.

If you carefully use the lock, the link will probably be fine, it is when you turn the key to manually unlock the door if the battery is dead or you turn too hard. Normally you turn against spring tension to activate a switch in the door lock actuator.

I had this exact same dilema surfing in SoCal. My E39 has the valet key which has a metal blade, and I'd put it in the hook inside my wetsuit. This became a pain so now I just drive my cheap Toyota truck and use a hide-a-key.

Tischer said they were forbidden by BMW to sell keys online any more. I've heard the same from other places. They really want you to order at the dealership where they can verify ownership. The other option is to buy blanks and reprogram your ECU.

Not true, BMW NA has told the dealers there should not sell keys online because they are concerned about ownership, however, we are talking about 10+ year old cars here and anyone can alter documents even if the order and pick up in person.

Keep in mind the Service Manager and Parts guy can be held criminally responsible if they do not vet the ownership documents whether the keys are sold in person or online.

What jmo69 stated above is correct, these guys are still selling online and helping the community out.

That's great to hear, thanks. I've been holding off buying an extra key for my daughter's car because of the crazy dealer prices. I ordered one from bimmerzone a couple years ago for my car but even they said they couldn't sell them any more.

Send them an email and they will tell you what supporting documents they need.

I think Sean was the primary contact?

Last time I bought a key from them I emailed photocopies of my driver license and car registration.

Wow, I guess I got it easy. Just recently bought a new OE diamond key for $125 from a local mobile locksmith. He came to my residence, program it, cut it and did whatever it needed to start the car..all in 30 minutes. Even cut me a spare key for free. Didn't bother to ask me for any proof of ownership or registration either.

Yes they can do this by hacking the computer to add new keys. When you buy keys from BMW, they issue a key that is already programmed for your car, or rather one that your car is already programmed to work with. When you hack the computer like this you may prevent BMW from being able to issue a new key. Obviously I'm oversimplifying the process, but is essentially correct.

I doubt it was an OE key, as only a dealer can order one. Most likely it's an ebay key with transponder.

If it was indeed hacked, what other negative implications should I be aware of?

I guess it was an OEM key then since it's missing the BMW logo on the back side but it does have "BMW" stamped on it.

Not even OEM, just an aftermarket one probably Chinese made.

^ perhaps. As long as all the buttons work and start the car, I'm good. It even works with the seat memory system.

I believe the only concern is not being able to get keys from BMW. Probably won't affect you since you know about it, but after you sell the car it could make someone unhappy if they spend the money on a BMW key and it doesn't work.

Does anybody know if you can pair a key fob from another E46 to your car. My 2 year old key just stopped remotely unlocking the doors. At the same time the door lock broke....which I just replaced....remote doesn't still work. I have checked all fuse and paired, paired and paired.
So I wondered if I used a working key from my other E46 by first inserting the original key in the ignition and turning it, removing it and then using the second key to pair. If it works then at least I know its the original key and yes I will have to re-pair the second key to my other car.

I actually went to the dealership a few years back with this exact same question - they said that the key needs to be made new and you can't send another key in to get matched to your car. Not sure if that's totally legit but at the end of the day, I think that's the only plane you can obtain a full functioning key, so... keys are getting mega expensive

You can use the keyfob portion of a key from another car, you cannot use it in the locks because it is cut differently and the EWS will not by in sync with your car. The problem is the battery will not be getting charged so it is just a matter of time before the battery starts to get weak.

But you might as well just buy a ebay keyfob and sycn it to unlock your car.

You can even just the metal key blade off and use it like an old school keyfob.

At least the ebay keyfobs have replaceable batteries from what I have seen.

Your idea of trying to get a key from a different car to work is pretty much a waste of time for many reasons.
