If your key fob stops working, it can be a frustrating experience. But before you panic, it’s worth knowing that there are several common reasons why car remotes become unresponsive, and many of them have simple fixes. In this article, we’ll address the question “How do you fix an unresponsive key fob?” by exploring the five most common causes and what you can do about them: battery issues, need for reprogramming, damaged transmitter or receiver, damaged components, and intermittent faults.
Reason N.1: No Battery
Most key fobs are powered by lithium batteries that can last several years. However, they will eventually need replacing. If your car fob becomes unresponsive, the first thing to check is the battery.
Reason N.2: Needs Reprogramming
For your remote to function correctly, it needs to be paired with the vehicle’s receiver. If this pairing becomes corrupted, typically due to a low battery or shock, the key fob will fail to operate.
You can often reset the remote by following the sequence outlined in your car’s user manual. If resetting doesn’t work, you’ll need to have the key fob reprogrammed by an automotive locksmith or your car’s dealership.
Reason N.3: Damaged Transmitter or Receiver
Your key fob works by exchanging signals with a paired receiver in the car. If either the transmitter in the fob or the receiver in the car is damaged, the remote won’t function properly. This damage is often due to physical shock or water exposure.
Diagnosing this issue can be challenging since the symptoms are similar to those of a pairing loss. Try resetting the remote first. If that doesn’t work, contact an automotive locksmith.
Reason N. 4: Damaged Components
Although key fobs are designed to be durable, extreme trauma can damage their internal components. If your remote stops working after being dropped or exposed to water, it’s likely that the internal components are damaged.
In such cases, it is usually more cost-effective to replace the remote.
Reason N. 5: Intermittent Fault
If your remote works only intermittently, it’s often a sign that the battery is running low and needs replacement. It’s easier to replace the battery while the remote is still working.
If a new battery doesn’t solve the problem, the issue may be due to interference from another vehicle or a faulty transmitter. Contact your local automotive locksmith to diagnose and resolve the problem.
