Where is the security sensor located at in 1997 Buick Riviera The light usually blinked on and off when getting car now it will blink then stay not start until?

The security sensor in a 1997 Buick Riviera is located on the passenger’s side of the car, behind the glove box. The sensor is a small black box with a green light on the front. When the car is armed, the light will blink on and off. When the car is disarmed, the light will stay on solid.

If the security light is blinking and the car will not start, it means that the sensor is not detecting the key. This can be caused by a dirty key, a faulty sensor, or a problem with the wiring.

To troubleshoot the problem, first try cleaning the key. If that doesn’t work, you may need to have the sensor or wiring replaced.
