Lotus elise 2005 fob and key does not work

Re-synchronize the FOB if the problem is with just one key.

1. Hold down both buttons simultaneously until the fob LED goes out. (10 seconds)

2. Release both buttons -- the LED should come on and stay on.

3. Press the larger fob button for a second, and the LED should flash.

IF re-synchronization doesn't work, you may have to replace the fob. Call customer service with your PIN (on the key-card that came with the keys). IF you don't have the PIN, then you need to call customeor service to confirm/register your ownership of the car.

If the keys are re-synchronized and it still doesn't work:

Re-program.

1. Re-synchronize as above, if you have not done so.

2. Turn the ignition on 3 times within 7 seconds. The red light above the odometer should light and stay on for 3 seconds.

3. Enter the PIN. Immediately after the red light goes out as per 2 above, switch on the ignition and count the number of flashes until it equals the number of the first digit on your PIN, then turn the ignition off, then on again. Do this for all four numbers.

4. What a pain, but if you get it wrong on a count, then you can restart by turning the ignition off for 10 seconds.

5. After the fourth digit, if the PIN is correct, the red light will stay on. Then you can re-test the fobs, and it should work.

Otherwise, call customer service.

Hope this helps.
