Mega problem?

[macey]

Hello, I have a 2013 Elise S (2ZR-FE engine). Glanced inside the other day and noticed that the immobiliser was not flashing, "strange" I thought. Battery flat? Only did 1,500 fault free fantastic miles in it two weeks ago. Took the front panel off today and jumped a fully charged battery to it. Nothing! Can't  open the door, can't get into the engine compartment either. Alslo noticed that the RPM counter is stuck at 2,500 rpm. Looks like a major ECU/computer failure to me. Any ideas here? What the fcuk am I going to do? Help much appreciated.

I would try manually opening the door with the key then removing battery for a short period.

 

i encountered some strange issues with other cars when the battery was faulty.

not an option with this car.

I'm not sure as I don't know the Elise layout, but if you could jump it, can you get access to the battery?

I finally managed to get into the car, I jumped it with a fully charged battery via the two jump points under the front panel. Couldn't undo the driver door from outside, undid passenger door and removed roof. Only remaining problem is driver door only opens from inside. Tried key in lock, wont turn anticlockwise from vertical.

Door only opens from inside, help appreciated.

That really sounds like a mechanical issue with the door tumbler. I can't see how a power issue could muck up something that is essentially mechanical.

Does the resistance feel different on the driver/pax doors, pressing the button? You can tell if the deadlock are engaged this way, there should be no resistance if they are.

Trying putting the key into the drivers side with the door pin all the way up and try twisting the key again? It's hard to pull up, but do it. 

You can also try cycling the CDL switch on the centre control (rocker switch) to see if that makes the pin go up?

Also, remove the key from the ignition, remove the battery negative and charge the battery. When you remove the charger and reconnect the battery negative the rev counter should reset.

Sorted, found out how to unlock with key (even though never have locked it with the key). Key in lock, button in, turn to right. End of problem. To summarise, flat battery, jump lead not connected properly due to restricted access on car 'jump posts', Second attempt disabled immobiliser, opened passenger door, took roof off because couldn't get in via passenger door due to restricted access, got into car after opening driver door from inside, figured out how to unlock driver door with key.:)
