1. Battery Problems
Symptoms:
No response when pressing buttons
Weak signal or requires standing close to the car
Solution: Replace the fob battery—usually a CR2032 or similar coin cell. Check your car’s manual for the correct battery type and how to open the fob. Don’t forget to clean the battery contacts while you’re at it.
2. Signal Interference
Symptoms:
Fob works intermittently or not at all in specific areas
Works fine again when moved away
Solution: Avoid parking near large metal objects, wireless transmitters, or other electronics that could block or interfere with your fob’s signal. If issues persist, the fob’s transmitter might need recalibration or replacement.
3. Worn Buttons or Internal Damage
Symptoms:
Physical buttons feel soft or unresponsive
Only some functions (e.g., unlock vs. trunk release) work
Solution: Internal circuit wear or water damage may be causing malfunction. If the fob has been dropped or exposed to moisture, bring it to a locksmith for inspection and cleaning—or order a replacement shell if the circuit board is intact.
Reprogramming Needed
Symptoms:
New fob doesn’t work
Fob stopped working after battery change or vehicle repair
Solution: Some fobs lose sync with the vehicle and need reprogramming. This may require specialized equipment—perfect job for a professional automotive locksmith (dealers aren’t your only option!).
5. Vehicle Receiver Issues
Symptoms:
Fob works with other vehicles but not yours
Car doesn’t respond to any fob, not even spares
Solution: The problem may lie with your car’s onboard receiver or wiring. This typically requires dealership diagnostics or a trained locksmith with OEM-level tools.
