Where Is the Anti-Theft Fuse Located?

Q: Where Is the Anti-Theft Fuse Typically Located?

A: The anti-theft or car alarm fuse is usually found in the fuse box on the driver’s side. It should be directly in front of your left knee covered by a plastic panel.

In some vehicles, the anti-theft fuse can be in the fuse box under the hood that’s also on the driver’s side. The fuse box should be behind the air filter.

For Ford vehicles, the anti-theft fuse isn’t labeled, so you’ll have to refer to a specific reference number to find it.

Sudden impact or motions inside the vehicle can trigger the anti-theft alarm. Usually, the alarm has a security light that stays on even when the engine is off. The light should go off once the engine starts.

Depending on the vehicle’s specifications, the anti-theft alarm can also prevent the engine from starting. It can also lock you out of your vehicle under certain conditions.

Tips on How to Access the Anti-Theft Fuse

The exact location of the anti-theft fuse should be in your owner’s manual. Once you locate the right fuse box, there should be markings on each of the fuses or color-coded plastic covers. These covers usually have numbers on them that correspond to a specific circuit.

If you’re planning to disable the alarm, you’ll need a fuse puller or pliers to disconnect the fuse.

Never use a higher amperage fuse than the anti-theft fuse calls for. If the fuse is blown, it means that something else had been working too hard and pulling too many amps.
