You press the unlock button on your key fob and nothing happens. Press it again. Nothing. In the cold, fob batteries give up more often, and a dead fob can feel like being locked out of your own car. Most of the time, there's a backup way in.
First: is it the fob or the car?
- Do the car's lights flash or anything respond at all? If the car is completely dead too (no dome light, no dash lights once inside), the car battery may be the problem, not the fob.
- Does the fob's little light blink when you press a button? No light on a fob that usually has one points to a dead fob battery.
- Do you have a spare fob at home? If the spare works, it's the fob.
Step 1: Find the hidden mechanical key
Most key fobs have a small metal key tucked inside. Look for a little slide or button on the fob; pressing it lets the key slide out. It's easy to forget it's there.
Step 2: Find the hidden keyhole
Many newer cars hide the driver's door keyhole under a small plastic cap at the end of the door handle. Check your owner's manual (or the manufacturer's website) for your model; often there's a small slot on the underside of the cap where the metal key can gently pop it off.
Step 3: Expect the alarm
Opening the door with the metal key can set off the alarm on some cars. Don't panic. It usually stops once the car recognizes the fob at start-up.
Step 4: Start a push-button car with a dead fob
Push-button cars have a backup for exactly this. On many models, you hold the fob right against the start button (or place it in a marked spot in the console or cupholder) while you press the button. The car reads the fob's chip even when its battery is dead. Your owner's manual will show the exact spot for your vehicle.
Replace the fob battery
Most fobs use a small coin battery. Check your manual for the exact type. They're sold at most grocery, drug and hardware stores, and many fobs open with a small screwdriver or coin. Replacing it every few years, before winter, saves you this hassle.
When the car battery is the real problem
If the fob is fine but the car won't respond at all and the dash stays dark once you're inside, the car battery is likely drained. That calls for a jump start, and if the battery is old, a replacement.
When to call a pro
- There's no hidden key, or it won't turn
- The door won't unlock with the metal key
- The keys are locked inside the car
- The fob is lost, not just dead
