Is the Key Fob Really the Issue?
Before diving into the troubleshooting process, let’s see if your key fob is actually the problem. Luckily, it’s easy to narrow the issue down to your key fob. All you have to do is to check the power lock switches in your car. If they’re in good working order, then your fob needs to be looked at. If the power lock switches are acting erratically, then you may be dealing with a faulty lock actuator or an electrical problem.
If you’ve determined that your key fob is indeed the problem, let’s go over the 3 most common Chevy key fob issues:
1. Failing or Dead Battery
Sometimes all it takes is a battery replacement to resurrect your key fob. You can either change the battery and see if it does the trick or have your fob battery tested at the battery kiosk at the nearest auto parts store.
If your battery is failing, then replacing it will put your fob back in working order. If your battery is completely dead, then the fob’s chip has lost power and needs to be reprogrammed. You can either reprogram it yourself (here’s a reprogramming guide for Silverado models) or have your local Chevrolet dealership do it for you.
2. Fried Circuit Board
Was replacing the battery unsuccessful? If you haven’t already, get your fob battery tested. If the test results show that your battery is dead but the battery replacement didn’t work, then you’re likely dealing with a fried circuit board. Maybe you accidentally spilled liquid on your key fob, or maybe you left it out in the rain. Maybe your fob was dropped or thrown against something hard. If a fried circuit board is the culprit, then you have to order a new circuit board and have your Chevy dealership install and reprogram it for you. You even can see if a reprogrammed circuit board is available for your model.
3. Worn Casing
Sometimes normal wear and tear takes a toll on your key fob’s performance. A worn casing can disconnect some of the internal components from each other and disable the signal. If you’ve determined that the casing is the culprit, then ordering a new casing and transferring over the circuit board and batteries should do the trick.
