1997 Disco SE…. Rover won’t let me start her due to security system (red light flashes on dash). The doors all open simultaneously but the security stays on so can not start. It was beeping too but stoped that and doors open but can’t start.. I think I overwhelmed the truck by starting and stoping 5 times in about 20 minutes. Guy tried to help said to turn key half way for 15 minutes and it should reset it. Didn’t work. Tow guy was honest and said only can go to Dealer to reset the computer to take off security. Can you reset it yourself? Help please …Thanks.

 

Sorry guys.....realized late how stupid it was to ask for this. I would have deleted it if I could figure out how.
