I have 1 key that works on my X5 but the battery is dead in that key.
I bought 2 key's from ebay and had them cut to match the OEM key.
I can open the doors with them and turn the ignition but I can not start the car.
Is it possible to program a key from another BMW so it will work on my X5?
I have a key from my old E46 BMW that is the same key as my X5 key, but can it be done?
