Dead Key...

Decided to use the spare key for a change tonight and as I know they need to be charged from time to time....

turns out I was too late it is dead :oops: So Drove for about 10 miles (supermarket run) but it still doesn't work...

So how long should it take to charge the key up? and when charged does it have to be programmed back to the car or not?

Thanks in advance :D
 
Freaky - I was just about to start a post on this exact subject, as I have the exact same problem..

I had one key transponder die, then after switching to spare its just not charged, and ive been using it for a week now..

Although, im only doing approx 4-5 miles per day..

Do you have any pics of Alpina front spoiler?

I am toying with the aero kit, got the rear last week off ebay. Problm is I have seen so many I just can't decide what to go for. Alpina expensive?

I also had this. when I booked my car in for it's inspection 2 at Autologic BMW Indi garage, he basically carried out a process of pressing buttons in a particular sequence then it worked perfectly and has done ever since not sure what the process is as he did it so quick.

and it was free ! another plug for a great BMW indi

sounds like he programmed the key then :D

I have that procedure somewhere - I will fish it out tomorrow and give it a go 8)
 
I always use both my keys as well. One during the week, the other on weekends just to keep them both charged up and in sync.
 
The manual (for the E89 but I'm sure they are similar) says to charge on "Long Drives". I don't think 4-5 miles a day qualifies.
 
Hi Russ,

Do'nt have any pics of it on the car, as I've not actually got around to fitting it yet.

I'd imagine it would look pretty good with the rear aero kit. Just try Google, loads of alpina pics on there.

If your looking for one, I could be persuaded to sell mine, looking to sell the zed soon, and I'd rather sell the car in OEM spec.

where is this chappy?

i use both keys to keep them charged, i recall reading it said spare key should be used at least every 6 months
 
Surely reprogramming the key would only be necessary once the battery is charged. Assuming that once its dead, the key loses its program, then requires reprogramming..

Will go for a long drive today, and give the reprogamming a go.

Found it on Yahoo answers.... (Copied and Pasted below) Procedures below.. I tried the first and it didnt work for me, but the process for doing it with No working keys, was fine.. Really simple to do...

"

To carry out this procedure you need to have one working key and one key which requires programming. Please read on if you do not have a working key as this is also covered further down. It may help sometimes to hold the key close to the rear view mirror as this is where the sensor is located in most models.

1. With both keys, get in the car and close all windows and doors.

2. Put working key into the ignition and turn to position 1 (the accessories should turn on)

3. Turn the key back to position 0 and take the key out of the ignition.

4. Using the working key, hold down the unlock button, press the BMW logo (lock button) 3 times, and release the unlock
button. Doors should lock and unlock.

5. With the new key, hold down the unlock button and press the BMW logo (lock button) 3 times and let go of the unlock button. Doors should lock and unlock and you're done!!

Alternate Procedure:

1. Switch ignition on and off within 5 seconds, with all doors closed.

2. Take key out of ignition and press unlock button. Hold unlock button whilst pressing the lock button 3 times, all within 10 seconds.

3. Release unlock button.

4. The system recognises re-programming by locking and immediately unlocking the doors.

5. You have to do your other keys within 30 seconds after reprogramming your first key by following steps 2,3 & 4 only.


Alternate procedure if above doesn't work or if you do not have a working remote:

1. Turn key to position 1 five times very quickly
2. Remove key
3. Hold unlock button then press lock button 3 times, release unlock button.
4. If you have another key do the same button pressing within 30 seconds
5. Turn on ignition to finalize

Older 3 Button Key (E36, E38, E39)

Remote Key Re-Initialise - If a key fails to operate remotely, it will have to be re-initialised (all keys in sequence at the same time)

1. Get in and close all doors
2. Turn the ignition on & off quickly (no more than 5 seconds) to start the process. Next action must take place within 30 seconds
3. First key - hold down button #2 (unlock - on the bottom left with the key blade pointing up) while striking button #1 (lock - the BMW logo) three times. Release button #2. This should be confirmed by door lock operation.
4. If you have more than 1 key then you need to repeat for the other keys within 30 seconds of first or they will be rendered inactive.
5. After last key then cycle the ignition on/off to finalise the process (it is not necessary to start the engine).

Both keys should now have new randomly selected security code words - assigned by the car's system.
Those codes will be continuously incremented within the new sequence each time you hit a button. It is when they get out of sequence with the car that they loose the capability to be recognised and you then have to do this again.

This occurs when you take longer than 1 minute changing the battery, or if you hit the buttons more than 1000 times when it is out of range of the car.
