When you say it will not start are you saying it will not crank over or it cranks but does not start and run?
If the immobilizer can not read the key then yes it will not allow the car to start, that being said in most cases the system will set and store a fault code and or codes. Are you sure there are no fault codes setting? Have you tried your spare key, try switching keys, wait 10 to 15 seconds before trying a different key in the ignition and see if that will allow it to start.
It will crank and not start and as I stated, the system will usually set and store a fault code and or codes.
