Here are the steps:
Erasing Existing Programming:
1. Turn the ignition to the "ON" position, and ensure that the dash lights illuminate, but do not start the engine.
2. Quickly turn the ignition from the "ON" to the "OFF" position four times within a span of 5 seconds.
3. Note: If performed correctly, the dash lights should flash rapidly to confirm the erasure of existing programming.
Reprogramming the Key:
1. Insert the key you want to reprogram into the ignition and turn it to the "ON" position, ensuring the dash lights illuminate.
2. Quickly turn the ignition from the "ON" to the "OFF" position four times within a span of 5 seconds.
3. Note: If performed correctly, the dash lights should flash rapidly again, confirming the start of the reprogramming process.
4. Leave the key in the ignition for at least 15 seconds until the security light turns off (may take longer).
5. Turn the key to the "OFF" position and remove it from the ignition.
6. Repeat the above steps with any additional chip keys you want to program.
After completing these steps, the chip-equipped keys for your 1998 Toyota Camry should be successfully reprogrammed.
