yes,go to parts house look for tool to plug in to your cig.lighter it has the plug in for a 9volt batt.on it,this will keep enough power the e.c.m. so the program will not be lost. Actually you don't have to 'reset' it. It is very common for the battery terminals to be disconnected for various maintenance activities. That action is no different than replacing the battery. I actually replaced my battery in my 2000 GLS 2.0 two weeks ago. No problems. If you mean the head unit, the code is in your manual, just enter it in after your replace the battery.
Not true. The computer does not have to be reset. You can change it yourself. You may have to enter the radio code if it is a theft deterrent radio but you have to do nothing to the computer.
You have to take it to a dealer. Something about you can fry the computer if you do it wrong.
You take it to a dealer. The computer on the X5 needs to be told a new battery has been installed. Essentially the new battery needs registered to the vehicle.
no after changing drive vech for 3 miles
The only way to unlock it is to go to the dealer and let them put it on the computer to get the code.
Right side of the engine, next to the battery department. It has a little cap, can't change it yourself have to take it to the dealer to have it changed...
I was informed by a BMW dealer there isn't a battery to replace and you have to order a new remote and then have it programmed by the dealer.
The dealer can "flash" the computer for any up dates or changes but it is not possible to do this yourself.
It should be under the dash between the radio and accelerator. You can change it yourself, but it will have to be programmed by a dealer or mechanic.
dealer has to do this. A good locksmith may be able to also.
Change battery at official dealer.
If the computer is invovled, it is a dealer install only.
