Weak Signals

If your key fob doesn't respond to the buttons on the remote it could indicate that the signaling is not working correctly. Radio signals are used to transmit information between your car and key fob. Poor or inconsistent radio signals can lead to poor performance and a limited range.

One of the first things you should examine is whether your fob's battery is low because this could significantly impact signal sensitivity. Resetting the settings on the fob could aid in restoring a more consistent response. The process will vary from vehicle to vehicle. The owner's guide or a call to your manufacturer's support number is your best resource.

Other factors, such as interference from other devices operating on the same frequency can also cause weak signals. Other key fobs and wireless communication devices could interfere with the radio frequency (radio-frequency) signals your key fob sends to connect to the receiver of your vehicle.

Finally physical damage to your key fob can also interfere with the transmission of RF signals, which could result in a decrease in range and performance. A blown fuses, a damaged or cracked button, or a bent case of the fob may affect the transmission of signals and cause the remote not to function properly.

They can identify the issue and suggest the best way to proceed.

Physical Damage

The most common reason for a car key fob not working is an inactive battery. These small devices rely on tiny lithium-ion button or coin batteries to function. These are easily replaced and can be found at most pharmacies, grocery stores and shops that sell electronic products.

Most fobs require CR2032 batteries. However, yours may need a different type.

If none of the solutions above work, you can try this trick: disconnect the battery from the car and the fob for a short period of time and then reconnect them in a reverse order. This could trigger a restart within the system and in some cases this will fix the issue without having to do any of the other steps.

Keep the fob away from water or other sources of damage while experimenting. The fob is tough but you need to take care with it to ensure it lasts for as long as you can.

If the above troubleshooting suggestions do not help, it may be time to think about replacing your key fob. If it's been dropped, trodden on or subjected to other extreme environmental conditions, it could be damaged beyond repair and in need of a replacement. Look around for the most competitive price.

Lost Fob

Even with the best care it's a fact of the road that car key fobs may occasionally cease to function. If you lose yours, it can be extremely expensive to replace it, particularly if you don't have a spare. "You might end up paying $50 or more to get an alternative from the dealer and have it programmed, as well as an additional mechanical backup which could cost you at least another $100," says Mel Yu an automotive analyst with Consumer Reports.

That means that locksmiths need an exclusive programing tool that only the car manufacturer has, which adds to the overall expense.

In the majority of instances, you'll have to pay for the entire service at once, which includes any charges to reprogram the new key fob. This can range from $20 in certain stores to more than $200 at dealerships for cars, based on the model of vehicle.
