I'm having a problem that I have not been able to research, on this forum as well as in the Lotus service manual and cobra detailed manual.

My car seems to work normally but I need to program a new key. So I set the immobilizer, get the red light blinking. Then cycle the ignition 3 times. Red light stays on 3 seconds just like it's supposed to.

Then when I turn the key back on, I'm supposed to see the blinking light for the PIN. Instead, I get a single long beep that lasts about 15-30 seconds. After that it just goes back to blinking as though the alarm just got set.

I've checked the position of the light. The alarm seems to work normally with respect to the motion sensor. It doesn't signal any issues when I lock the car, just the normal two beeps.

I'm not sure what to do next--and can't find any reference to this issue.

Thanks in advance for any help folks can provide.

Firstly you have to disable/disarm the immobiliser/alarm before starting

Press and hold both buttons on remote until the LED stops flashing (about 10 seconds).
Do this for all remotes to be programmed
The LED on the remote should stay on until after programming.
If the LED on the remote extinguishes by the time you want to program, the key has gone into battery
saving mode, press large button once to bring the LED back on then proceed with programming.

STEP 2 – ENTER PIN
1) Turn ignition ON and OFF 3 times within 5 seconds.
2) Security LED will blink once indicating that the security code can now be entered.
3) Enter security code as follows:
.... a) Turn ignition ON & count number of blinks representing 1ST digit of code then turn ignition OFF.
.... b) Repeat for 2nd digit.
.... c) Repeat for 3rd digit.
.... d) Repeat for 4th digit.
4) Turn ignition ON and LED will come on permanently if correct code has been entered

STEP 3 – COMPLETE THE REMOTE KEY FOB PROCEDURE
1) Press and hold the large button on one of the remotes until the security LED light in the tachometer goes out then comes back on.
2) Do this for each remaining remote
3) Turn off the ignition and check each remote for the correct operation.
