Key no longer works, how do I replace & program a new key?

Hey guys,

My BMW key no longer works and very annoying I have to keep opening and closing with the key in the door.

What's the process around fixing this? Do I need to get a new key or change the battery in my existing key?

Thanks.

Thanx...I will try that first. Cause hubby accidentally did the roll windows down thing with my key but it won't lock the doors. We changed the program to not roll windows down when BMW north was here...but door locks didn't work

The link I posted was where I got mine, e-mailed a pic of my tittle and drivers license and they sent it out ready to go. It will start the engine but you will have to program the locks. No software needed, they have a video involves key turns in the ignition and pressing buttons on the key, very simple.

Any truth to the "10 keys made by BMW" story?

I keep reading about BMW making 10 keys for your vehicle when it was originally built. Supposedly they give you 4 when you buy the car (two remotes, a valet and a plastic "spare") and the other six are kept at the factory. When you order a replacement key it comes from that inventory, and if by chance you use more than 10 keys in a lifetime you have to pay some typical BMW priced fee to have additional ones made, or change your lock cylinders.
Can anyone confirm or deny this??
Thanks

Most of what you have been reading is garbage.

1. BMW does not make extra keys when the vehicle is built and keep them in a warehouse, this is some STUPID URBAN MYTH.

2. Not all cars were delivered with 4 keys, after 10/2003 the plastic "spare" key was dropped. Even if you want the plastic "spare" key and you have a car build after 10/2003 you cannot get one. There is no part number associated with the "spare" key.

3. The EWS does have only spots for 10 keys. If for some reason you were to ever exceed this, you will have to work around the EWS with a 3rd party programmer. BMW keeps count of the number of keys ordered and they will not provide you with a 11th key.

4. BMW has the key coding info stored and if you order a new key, they cut the key and the EWS has a baseline default starting code that the EWS will read without programming. If you order a new key, assuming the lock cylinders are original on your car, the key will fit the locks and start the engine without any further effort or tools. Only the keyfob needs to be learned by the car, this requires no tools or software.

5. You would be a fool to change lock cylinders. If you had a problem, best to buy a complete set of keys, lock cylinders and EWS from a wrecked car. BUT beware you will not likely ever to be able to purchase a new key for this system unless you somehow had the title to the wrecked car. But dealers want to see that you have the car registered and is registered in your name.

Hope this answers all of your questions.

This is the Internet, you have to be very careful what you read and believe on the Interwebs!

Cheers for debunking yet another urban myth!

Can't thank you enough for the info. Helps a lot with my issue. Just for the record, I received replies on Bimmerfest that said the story is true. I tell my kids the internet is a sewage pit with a few pieces of gold in it. You have to wallow through the "poop" to eventually (possibly) find the gold.

The reason I ask is I purchased a new key from my dealer a little over 2 years ago. It stopped working (as though battery was dead) and so I brought it back to my dealer. I know how to program a key and I also noticed that it didn't happen overnight, it slowly started losing power over the past couple of months. They claimed it wasn't under warranty so I am making a stink about it. They told me the keys last for about 2-4 years, which I thought was BS. As an engineer I also know that batteries have specific shelf life if they built this thing in 2004 an 11 year old battery which has never been used will not necessarily hold a charge, which is possibly why this one failed. The original key still works fine (very worn around logo and raised arrows are practically worn off so I know it is very old).
They finally agreed to send it back to BMW and if they deemed it defective I would receive a refund to purchase another key, if not I am out of luck.

Yeah, the 10-key made in advance is just nonsense. It is a derivative of the fact that each vehicle will accept a TOTAL of 10 keys in its program, which is plenty if programming space should additional keys be ordered from the dealer over a long period of time. But the idea that extra keys are "stored in some warehouse" is total BS, and if you think about this at all, what a waste of material and labor would that be? Incredible!

Batteries rarely fail in these keys.

You can test the keyfob with the Energizer keyfob tester at most auto parts stores. Some TPMS tools also can test keyfobs.

I need a new key because I can't lock my car. I am scared to use the door lock manually because of the nightmare stories I've heard. My center button doesn't push on my key . I'm gonna price it at the dealer and then try to compare to an online place. I'm just afraid to fork out $150 online unless they guarantee it is going to work.

I priced a new key at my local BMW dealership and it is $180. Even though my keys work, they are intermittent and the range is spotty. I would pay the $180 in a heartbeat if I knew they would program it and warrant that it would perform like designed. I am still considering this purchase although it is way down on my priorities list. But if mine did not work at all, and I knew it was the key and not the receiver, I'd do it. I WOULD NOT risk going to an aftermarket vendor or ebay, I think you'd be throwing your money away.

I fully agree with you. I already told my hubby that for $200 or less I'm driving to Syracuse to have it done there. I checked my key coding and I have five available key spots on my module so I'm good to go. The key worked to roll the windows down on accident so it is just the locking button that doesn't work.

Great = double check the stealership price - I've read a lot on this and they seem to vary greatly.

A few things here:

Mbryant616 the vert key range is very poor, maybe 25-30 feet unless you touch the key to the base of your chin when Locking or Unlocking.

Again, best to test what ever Fob you have at a parts store if you can find the tester.

A little known trick is if you can buy a cheap, used OE key of the same shape from any other BMW you can program the Fob to work with your car. But the battery will not charge up.

The other option is to just get a cheap Ebay key and program it just as the key Fob. I would just cut the keyblade off the fob and keep the fob on your key ring.

The ebay keys are like $15 and you can easily replace the batteries in these.

http://www.ebay.com/itm/315MHz-Keyle...9U3yVV&vxp=mtr

You could jump through all the hoops and get a locksmith to try to copy the key and cut it, then you could waste about $100 or so and buy a Asian key programmer and then figure out the software and try to make the key work with the car's EWS. BUT this is a LOT of wasted time, you would be far better off just buying a new Keyfob online from TheBMWPartsStore for around $150.

The other issue with the DIY key is if you are not careful you will use up keyslots in the EWS and if you ever order a key from the dealer, you may have to delete keys from the EWS.

SO

How do I know they key from the online store will be cut and coded correctly for my car. And then I have to do the in the key switch programming myself for the door locks or does it work out of the package.

Next question is how do I make a key fob without the key part from an eBay key. I would be glad to have one of those too...but I thot the only way to program them was to put in the ignition.

ASSUMING, and this is a BIG ASSUMING, the EWS and lock cylinders are original in your car and the VIN is correct, BMW has the keycode info on record based on the VIN. They cut the key using the keycode info and the EWS is set to a default value so all you need to do is put the key in the ignition and the car will start. You will have to program the keyfob to work with the car, BUT once you put the car in keyfob learning mode, ALL PRIOR keyfobs are erased, so if your current keyfob buttons do not all work, then it may be deleted from the car.

You buy the $15 ebay key and you just program the Fob to Lock and Unlock the car and you are done. Screw having the keyblade cut, you could, but as you may know the drivers door lock link is made weak to prevent theft and is NOT DESIGNED to be used daily. When this breaks, you are screwed BIGTIME with a Touring or Wagon as there is only 1 key cylinder for the car, there is no key lock for the tailgate. With the Windows Programmed NOT TO drop, you will have to break a window to gain access to the car if you cannot get a tool to press the console central locking button to unlock the car.

If you own an E46, here is what you MUST have otherwise you will be screwed and breaking a window in the near future.

1. 2 properly working keyfobs!!!! Buy 2 of the $15 Ebay keys if you are SMART!!!

2. A replacement/properly working console mounted central locking button.

3. A working drivers door lock cylinder.

4. A GM5 module with replacement relays!! This is not an IF, but a WHEN problem when the GM5 relays start to give you problems. My friend is the original owner of a 2001 325xi Touring and I had to replace the GM5 relays in her car 6 years ago when the car was 9 years old!!! Now the car did have the Auto Locking enabled so the door locks got a lot of activity.

5. A properly working drive door lock actuator!

Not a bad idea to have the windows roll down with the keyfob so if the door lock actuator or door lock link breaks you can get in the car. The ONLY problem is if the driver door lock actuator goes bad, you will come out and find the windows down and the sunroof open. This seems to happen more when it is raining or about to rain!!!

Good luck, welcome to the life of a 15+ year old BMW!!!
