jagarundi - Could you tell us what model & year you have (the best is to put in the signature line)? Spare key, are you using the keys with the remote OR the valet key? Does your car have a factory or aftermarket alarm system (voltage drain)? Have you used any code reader (CarlySoft is recommended)?
