What do you do if your Jeep Grand Cherokee will not start?

Answer 1

First check instrument panel to see if the SECURITY light is lit. If so, assume that something has triggered the anti-theft automatic motor cut-off. The easiest override is to use your key in the driver door and turn it RIGHT twice, and left once. Another contributor suggested the same procedure with the passenger door. If neither works, we tried a back-up plan and used two keys just in case...

First, we attached battery cables to insure power to the engine.. then attempted to start engine. Second person tried the key procedure on the driver door. It worked like a charm!

It's an ongoing problem with our 95 Jeep Orvis ed. ever since a professional battery outlet installed our new remote battery BACKWARDS and fried our electrical system. Always be very careful with those remotes. As for the non-start, if it's not the security cut-off, there are tons of other regular items to check, which I'll leave to others. Cheers!
