Default key replacement

Has anyone replaced a key recently? If so what were they asking? I'm trying to shop around but everyone is asking 200-250+, but if that's what it is then I might just have to do it.

My lock button is no longer working and having to lock the car manually isn't the highlight of my day.

Thanks

Some guys have been getting them out of dealers for ~$140-150 - if they looked around.

Saw a couple members quoting that but were out of state. Is it possible to fax the necessary documentation over to have them send it out and receive it at home or local pickup is also required? (If you know)

Mine was around $150 a year and a half ago. I submitted all documentation via email and had it sent to my home.

I donít need to get the key programmed to my car or anything? Everything works straight out of the box?

Read through the FAQ link I posted. I had to submit my registration and a copy of my driver's license and that was it. You'll have to do the recode sequence for remote entry on all your keys so everything matches, but otherwise it worked out of the box.

Default Re: key replacement

Depending on what you're trying to do, the info shared here may or may not work for you.

If you're replacing a key, then you should be able to crack open your current key, and pull the ignition transponder out and put it into the new one. The link in Randman's post will then allow you to code the new key to your car's door locks, and the transponder will work with your ignition security for starting your car.

If you need a NEW key, it's much more complicated (looks like ~$150 from BMW Mini Parts is probably one of the cheapest routes). The ignition system has to be programmed to the new key, and this is why it's so expensive at dealerships. This is not something that can be done with INPA or other software. You can buy a $20 key off eBay that will connect to the car's locking system just fine using Randman's link above, but it will never activate the ignition security until it's coded to the key's transponder chip.

To do that, you need a special chip programmer and a key reader, pull the module out from under the dash, attach the cable/connector to the chip contact points and program the key to the chip. I think it allows for a total of 10 keys, most of which are pre-programmed. I believe dealerships can send off to some central place (or Germany?) and have a key sent that corresponds to your car. Or they do the programming I'm talking about here in house.

The BMW Mini Parts Store appears to be doing something similar to what the dealerships do in terms of getting a key that's already been coded to your car. Apparently the transponder chip in the key can be custom coded if you know what codes are already programmed to your specific car. BMW must have a super-secret list of transponder chip codes for each car sold, and dealers and maybe some other specialty shops can access that as long as they verify certain info (ownership, etc.).

I spent about $150 on the hardware to do all of this, bought a few different blanks from eBay, and never got around to actually pulling the module to program the extra keys to my car. Getting the keys to lock/unlock was the easy part. Eventually I'll get around to the programming.
