The ignition module may malfunction, failing to engage the starter motor when the button is pressed. This could be due to a blown fuse or circuitry concerns.
4. ECU Malfunction
In uncommon cases, the vehicle's ECU may become malfunctioning, leading to interaction problems in between the fob and the ignition system.
5. Proximity Sensor Issues
The push to start system frequently includes a proximity sensor that finds the key fob's existence inside the vehicle. If this sensor is malfunctioning, the system may not trigger.
6. Relay Problems
A damaged or malfunctioning relay can hamper the electrical signals essential for the ignition module to operate correctly.
Diagnosing Push To Start Issues
Before continuing with Keyless Entry Repair work, it's necessary to detect the issue properly. Here's a step-by-step guide:

1. Key Fob Battery Replacement
Replacing a dead or weak battery is often the most basic option. A lot of key fobs can be opened using a small flathead screwdriver.
2. Key Fob Repair or ReplacementRepair: If the key fob is damaged, think about repairing it (if the damage is minor). This may need soldering, which demands ability and accuracy.Replacement: If the fob is beyond Keyless Entry Remote Repair, purchasing a replacement fob and reprogramming it might be necessary.3. Ignition System Repair
If the ignition module is defective, a professional mechanic can detect and change it. Alternatively, you may replace blown merges.
4. ECU Reprogramming
If the ECU is malfunctioning, it may require reprogramming or replacement. This procedure frequently needs customized diagnostic equipment.
5. Proximity Sensor Replacement
Replacing a faulty proximity sensor typically falls within the domain of a professional mechanic.
6. Relay Replacement
If the relay is defective, changing it is normally uncomplicated and can frequently be done at home.
