You can still unlock your car even with a dead key fob.

If you’ve just found yourself locked out of your car with a dead key fob, we may be able to get you going.

Remote key fobs are great until they fail. When they do, you may not be able to enter the car. Then, if you get inside, getting the car started can be foiled by a dead START button. We’ve got loads of solutions here, so find the one that most closely fits your scenario:

Swap the Battery

If your remote key fob has given up the ghost in the parking lot of a shopping center, you may be in luck. The battery may have failed, and getting it to work again might be as easy as replacing it.

To access the battery, you’ll have to open the fob. Typically, you have to use a coin or a small screwdriver to pry the battery cover open. The battery will look like a silver button. Look for the numbers on the battery and match those to a replacement battery.

Unlock the Door Remotely

Many manufacturers have remote door unlock services that can get you inside the car if your key fob is disabled, or if you’ve locked your keys inside. If your car doesn’t have an advanced remote unlocking system, roadside assistance can still get you inside. All of these services require that you have set them up ahead of time, and generally require a PIN. Here’s how to access those services:


Using the Audi MMI connect App, Audi owners can utilize remote unlocking services if the key fob is dead, or if the key is inside the car. You can learn more about the app and sign up at Audi’s website.

Unlock the Door Manually

Barring that, try holding your dead fob up against the driver’s door handle and pulling.  Sometimes there’s just enough juice in the battery to unlock it at a close distance.

If that fails, look closely at the fob.  If it has a leather jacket on it, remove it.  Almost all automakers hide a small mechanical key inside the fob.  There is usually a small catch that allows the spare key to pop out.  If you can expose the little mechanical key, you can then insert it into the lock opening in the driver’s door, and you’re in.

How To Start a Car With a Dead Key Fob

Once you’re inside, getting the car started is actually pretty easy. Automakers know that your keyless ignition may need to work if the fob dies, and the system has been designed to work even with a non-functioning remote. Some cars are equipped with a means of starting the car manually, and some have a backup built into the key fob that work without a key.

Even if your car has keyless entry, you may not have noticed that there’s actually a key slot somewhere on the steering column. Mazda vehicles, for example, are equipped this way. The “switch” you turn is actually a plastic cap that pops off, revealing a key slot underneath.

Here’s an example on the Ford Focus:

If your keyless entry works with a START button and there’s no mechanical key slot, there’s still a way to start the car. Use the key fob to push the START button. Some manufacturers have a backup system that allows this method to work if the key fob battery is dead.
