2001 BMW 325xi wagon setting alarm without the key?


Original owner, both keys will not recharge. New key is $125. I can use the key in the door to get into the car and turn ignition on but key does not recharge. This is NOT a battery issue, the key is the battery, if you don’t know this google it. I want to know how to set alarm without the key? Alarm is there, works but can’t set without key? I am looking for a work around and I’m cheap, like Click and Clack.
