Is It Possible to Deactivate a Key FOB That Was Stolen

Re keying a door lock of a residential door, and replacing old lock with a new high security lock

Losing a key FOB can be distressing, especially if there’s a chance that the thief knows where your car is parked. 

Let’s go through your options if you find yourself in this situation.

What to Do When Your Key FOB Is Stolen:

Before you panic, be sure to check any places that your car key may be. Retrace your steps to decide whether the key is actually stolen. 

It’s best to stick with your vehicle until someone can bring you a spare key as this will reduce the chances of someone trying to steal it. However, if you feel unsafe, contact your local security company or the authorities. 

From there, the next step would be to deactivate your key FOB

Steps to Take to Deactivate a Key FOB:

If you have a spare key FOB, you can take your vehicle to a dealership for deactivation and reprogramming. However, a local locksmith will be able to assist you with this at a more affordable rate. They’re generally also quicker and can come directly to your location.  

Deactivating a car FOB means deleting all keys from your car’s memory. A new FOB can now be programmed. It’s best to program a car replacement key at the same time if you don’t have one so that you’re not left stranded in the future. 

The only potential downside is that the thief can still unlock your car using the mechanical key, but this is highly unlikely since you will be near your vehicle. 

There is always the option of changing out your mechanical lock cylinder so that the key no longer works, but this is hardly ever necessary. What’s more, even if they did open your car with the mechanical key, your alarm would sound, which would send the thief running.

The only time you will need to take all these steps is if you know the thief knows exactly what your vehicle looks like, where you live, or if they are a threat to your personal safety.

Can I Deactivate a Key FOB Myself?

It is possible to deactivate a key FOB yourself, however, it’s not recommended. An incorrect car key programming process will waste your time and lead to safety risks. 

Deactivating it yourself will require you to refer to your car’s manual. Each car brand has slightly different deactivation requirements. You can also contact a dealership for instructions, but they will more than likely also discourage you from doing it yourself.
