Why Is My Remote Key Fob Not Working Consistently?
Remote key fobs are one of the most convenient parts of modern driving, until they stop working.
Whether it takes multiple presses to unlock your doors or your car fails to recognise the key entirely, an unreliable fob is more than just a nuisance. Left unchecked, it could leave you locked out, stranded, or even unable to start your car.
At Rush Auto Locksmiths, we specialise in diagnosing and fixing faulty remote keys quickly and professionally, wherever you are in Blackpool and the wider North West Lancashire area.
Common Causes of Remote Key Fob Failure:
1. Weak or Dead Battery
The most common culprit. A dying battery can cause your fob to work intermittently or stop altogether.
Solution:
We can replace the battery and test the key on-site to rule out deeper issues.
2. Fob Has Lost Synchronisation
Sometimes your key loses sync with your car, especially after battery changes or signal interference.
Solution:
Our locksmiths can reprogram your key to your vehicle’s ECU, restoring full function.
3. Internal Circuit Damage
Dropping your key or exposure to water can damage the circuit board inside. You may notice buttons that don’t respond or work inconsistently.
Solution:
We offer diagnostic testing and, where possible, internal repairs. If needed, we can cut and program a brand-new remote.
4. Faulty Receiver in the Vehicle
It’s not always the key’s fault, some vehicles suffer from receiver faults that prevent signal recognition.
Solution:
We’ll test both the key and the vehicle using advanced tools to pinpoint the issue.
5. Temperature and Moisture Effects
Cold, damp weather can impact the function of electronics, including your car key fob.
Tip:
If your key acts up in wet or cold conditions, get it checked before winter fully sets in.
