Common Causes and Solutions for a Toyota Aygo Key Fob Malfunction
Several factors can contribute to a non-functional key fob. Let’s examine the most common culprits and their solutions.
Dead Battery
The most frequent reason for a key fob not working is a dead battery. Over time, the battery inside the fob depletes, rendering it useless. Luckily, this is the easiest fix.
- Solution: Replace the key fob battery with a new one. You can find the correct battery type in your car’s owner’s manual or by searching online. Most key fobs require a small, flat, circular battery like a CR2032.
Key Fob Programming Issues
Sometimes, the key fob loses its programming and needs to be re-synchronized with your car’s immobilizer system. This can happen after a battery change or if the fob is exposed to strong electromagnetic fields.
- Solution: Consult your owner’s manual for the specific key fob reprogramming procedure for your Toyota Aygo model. Some models allow self-programming, while others require professional assistance. You might consider self program toyota push button key fob if your model supports it.
Key Fob Damage
Physical damage to the key fob, such as a cracked casing or broken buttons, can prevent it from functioning correctly. Dropping the fob or exposure to water can also cause internal damage.
- Solution: If your key fob shows signs of physical damage, you might need to repair or replace it. Contact a locksmith or your Toyota dealer for assistance.

Faulty Car Receiver
In rare cases, the problem might not be with the key fob itself but with the receiver in your car. This receiver is responsible for detecting the signal from the key fob and unlocking the doors or starting the engine.
- Solution: Diagnosing a faulty car receiver requires professional expertise. Take your car to a qualified mechanic or your Toyota dealer for inspection and repair.
Why is my Toyota Aygo key not working after battery change?
Sometimes, even after replacing the battery, your key fob might still not work. This often occurs due to the key fob losing its synchronization with the car’s system during the battery change process.
