My Car Does Not Crank At All !!!

If your Car doesn't Crank then it means 2 things, To find out what the problem is you must first Try Another Key, If the other Key Cranked the Engine and Started the Car, then this is a Key Issue and the Key needs to be replaced.

If You Tried your Second Key and you Still you don't get a Engine Crank at all, Then this Means that your EWS needs to be replaced.

If you only have 1 Key then there is no way to find out unless you send the EWS and Key to us.
