Changed battery on my fob key. Car still won't turn over. Every in the car works. Could it be my security code that needs to be reprogrammed?

Hello,

Can you upload a picture of the small red light that you are mentioning?
It can help us determine what the issue might be.

Did you have starting issue before the battery of the fob was changed?

It is possible to have the security system preventing the start.

Thank you.

My car is in the shop. The fob key has a new battery, but no crank- no turn. I have lights, radio etc., but my battery will not charge.

A triggered immobilizer will cause the electronics to function, but the engine will not start.
Many times, it can be reset by disconnecting the battery.
