1999 Toyota 4 Runner's keyless entry (with new battery) will not unlock the car. The "lock" button works fine. Using the manual key for entry triggers the theft alarm. The only way to stop the alarm is by using the unlock button on the remote, which as stated, is not working. It does not make sense to me that I cannot use the standard key to enter the vehicle. In essense, I am locked out of my own car. Any help is appreciated.
