1. Key Issues:
* Try all your keys: Does the problem occur with all your keys? If only one key causes the problem, that key's transponder is likely faulty and needs replacing or reprogramming at a dealership or locksmith specializing in automotive keys.
* Key Battery (if applicable): Some keys have internal batteries for the transponder. Replace the battery if needed. However, this is less likely to be the problem if the vehicle starts after a delay.
2. Passlock System Components:
* Passlock Sensor Ring (on the steering column): This ring contains the receiver for the key's transponder signal. Over time, the connections can become corroded or loose. Check the connection to this ring (you'll likely need to remove some trim pieces) and ensure it's clean and secure.
* Passlock Module (located near the ignition): This module processes the signal from the sensor ring. It's more difficult to access and test directly without specialized equipment. A faulty module is the most likely cause if the key and sensor ring are fine.
* Wiring: Check all wiring connections related to the ignition system and Passlock module for any damage, corrosion, or loose connections. Look for broken or frayed wires near the steering column and ignition switch.
3. Other Considerations:
* Battery Voltage: A weak battery can sometimes cause intermittent issues with the Passlock system. Have your battery tested.
* Vehicle History: Any recent work done near the steering column or ignition switch? Poorly installed aftermarket parts could interfere.
Troubleshooting Steps:
1. Start with the simplest: Try all your keys. Clean the ignition switch contacts with contact cleaner (follow instructions carefully).
2. Inspect the wiring and connections: Carefully examine the wiring harness around the steering column and ignition switch for any signs of damage.
3. Consider professional help: If you're not comfortable working on your car's electrical system, or if the problem persists after checking the easy things, take it to a qualified mechanic or an automotive locksmith. They have diagnostic tools to pinpoint the faulty component (module, sensor, or wiring).
Important Note: Don't attempt to bypass the Passlock system. This is generally unreliable, can damage your vehicle's electronics and will likely be seen as tampering if you try selling the vehicle. Professional repair is the safest and most effective approach.
