How can I get my key fob to start working again?

Asked by Jan 07, 2016 at 05:05 PM about the 2009 Chevrolet Silverado 1500 LT1 Ext. Cab

Question type: Maintenance & Repair

2009 Chevy Silverado 1500 LT 5.3 engine. My key
fob wouldn't unlock my truck, so I used my key to
open the door and my alarm sounded until I turned
my key over in the ignition. Display also shows that
my TPMS sensors sent working. Everything was
perfectly normal till my key fob stopped working.
What is wrong?

key fob might be a battery TPMS is your tire pressure monitoring system one of you tire pressures is not right

Battery in fob is working. I even tried my spare set of keys. It's not the keys, and I know what tpms is. I'm thinking it must be some sensor or something electrical.

TPMS is your Tire Pressure Monitoring System. Each wheel (including your spare) has one just inside the tire next to the valve stem. Discount Tire has them for about $68 a piece installed. I just replaced all for of mine last year. I drive a 2008 Chevy Silverado 1500.
