Can you reprogram a key fob thats already been programmed?
Key fobs are an essential part of modern vehicle security and convenience, allowing drivers to lock, unlock, and even start their cars remotely. But what happens if you need to reprogram a key fob that has already been programmed? Whether you've purchased a used car with an existing key fob or need to reset it for security reasons, this article will guide you through the process and considerations.
Understanding Key Fob Programming
Key fobs are programmed to communicate with a specific vehicle using a unique code. This ensures that only your key fob can operate your car. Reprogramming a key fob that has already been programmed is possible, but it depends on the make and model of your vehicle, as well as the type of key fob you have.
When Might You Need to Reprogram a Key Fob?
There are several scenarios where reprogramming a key fob might be necessary:
- Lost or Stolen Key Fob: If a key fob is lost or stolen, reprogramming ensures that the missing fob can no longer access your vehicle.
- Used Vehicle Purchase: When buying a used car, reprogramming the key fob ensures that previous owners or users cannot access the vehicle.
- Malfunctioning Key Fob: Sometimes, a key fob may stop working correctly and require reprogramming to restore functionality.
- Adding a New Key Fob: If you're adding a new key fob to your vehicle, reprogramming is necessary to sync it with your car's system.
Steps to Reprogram a Key Fob
Reprogramming a key fob typically involves the following steps. Keep in mind that the exact process may vary depending on your vehicle's make and model:
- Consult Your Owner's Manual: Your vehicle's manual often includes instructions for key fob programming. Look for a section on keyless entry or remote programming.
- Enter Programming Mode: Most vehicles require you to enter a specific programming mode. This often involves turning the ignition key to a certain position and pressing a series of buttons on the key fob or dashboard.
- Follow the Instructions: Once in programming mode, follow the steps outlined in your manual to sync the key fob with your vehicle.
- Test the Key Fob: After programming, test the key fob to ensure it works correctly. Check functions like locking, unlocking, and remote start (if applicable).

Frequently Asked Questions
When you program a new key fob, does the old one still work?
Will the old key still work? For transponder-style keys, while the actual metal key will likely still work to open doors, the key may NOT start the ignition, since the car has been reprogrammed to activate from a new remote signal (for safety purposes so that a lost or stolen key cannot be used to access your vehicle).
Can a magnet deprogram a key fob?
A magnetic key fob can become demagnetized due to exposure to an outside magnetic force that wipes its data. Sometimes, a fob might come close to a battery-powered electromagnetic device. As a result, it may have its data wiped that way. Other times, proximity to a simple kitchen magnet is enough to demagnetize a fob.
Can you reprogram a key fob that stopped working?
Reprogramming. Sometimes a key fob can develop faults, and the only way to fix it is to take it to the manufacturer to have it reprogrammed.
