Keyless Entry Warning Light On? How to Fix & Reset Keyless Entry Warning Light

Is your keyless entry warning light on, key fob not detected, push button start not working, or your car saying “key not detected” even when the key is inside the vehicle? In this video, I’ll show you how to fix and reset the keyless entry warning light, what causes the warning to appear, and what to check before replacing the key fob, battery, receiver, or keyless entry module. The keyless entry warning light can come on for several reasons. In many cases, the problem is caused by a weak key fob battery, dead key fob battery, damaged key fob, keyless remote not detected, smart key system warning light, keyless access system problem, push button start issue, or interference between the key fob and the vehicle. But sometimes, the issue can also come from a bad keyless entry antenna, faulty immobilizer system, low car battery voltage, blown fuse, bad start button, or a problem with the keyless entry control module. In this video, you’ll learn how to diagnose the keyless entry warning light step by step. I’ll explain how to check the key fob battery, how to start a car when the key fob battery is dead, how to reset keyless entry warning light, how to reprogram or resync a key fob in some vehicles, and how to know when the problem is not the key fob but the car’s keyless entry system.

Replace the key fob battery, test the spare key if you have one, hold the key fob close to the start button, check whether the doors lock and unlock with the remote, inspect the key fob for damage, and make sure the car battery is not weak.
