With the key? :) What do you mean?
Use you key to unlock the doors.
This is called "selective central unlocking" and is programmed under "Key Memory Options" by your BMW dealer.
I need a picture of the diagram for a 2002 BMW 325I
use a hammer..:)
The key remote for a 2002 745i requires a computer at the dealer to program it. The vehicle owner can not do this at home.
Hope this may help u... http://www.bimmerfest.com/forums/archive/index.php/t-80489.html
There's a key hole on the trunk lid. There's a regular key inside your remote. Get the regular key out, stick it in the key hole, and turn it all the way to the left - much farther than you normally have to turn it.
A new key for a BMW can be obtained by contacting your local BMW dealer. They will contact the factory in Germany that will make you a new key for your BMW.
It sounds as if the ECW chip inside you key is bad. this is the chip that talks to your car and tells the vehicle that the key is the proper key. The cut of the key is right so it will unlock the tumblers, and let you turn the ignition switch, but the car needs that signal from chip to tell it to start. you will need to replace the key at the dealership. about ($120-$190). The keys on websites wont work they may be cut right but only BMW has the key with the proper signal to start the car.
According to my owner's manual you must contact a BMW dealer to replace the key.
Turn key on engine off then pump gas to floor 4-6 times, it might work some other models done that way
