A Lotus Elise S1 does not have electric door locks, which is why an EKA code cannot be used and is therefore never delivered with the car.

When the alarm system is the standard Rover setup, a std. rover remote is delivered that opens / closes the system.

If Cobra setup, the Cobra alarm has its own immobilizer circuit and the Rover 5AS module is set to no automatic immobilise. This is done using a Rover Testbook but never had one in my hands though.

By using a Rover Testbook it should be possible to program new EKA codes and remote controls (as well as most importantly) change the time interval for automatic immobilising again.
It is this time interval that can be set to infinity and thereby the 5AS start circuit is deactivated and the Cobra alarm does the job with its own remote controls.

I have disconnected the power to my Elise S1 with Cobra alarm many times and every time the Cobra immobilizer has worked fine and the Rover 5AS alarm has remained disable.

However, it is a known problem that the Rover alarm system can jump back to active stage if you are very unlucky. This causes major problems for an Elise S1 owner with a Cobra alarm, as you have neither EKA options nor a Rover remote control. The only option here is the Rover Testbook, which is on the same level as finding the horn of a unicorn.

That is why this feature will make a difference in Pscan.

Please:
Can anyone confirm that the Rover Testbook has the option to set the time interval for automatic connection of the 5AS module to infinity?
