The remote unlocks the car but it won't start: causes and solutions
If the remote unlocks the doors but the car doesn't start, the problem may be with the immobilizer or the communication between the key and the vehicle's system.
Why doesn't the car recognize the key to start it?
Even if the remote works, ignition depends on the internal chip. Programming errors, battery problems, or interference can prevent the vehicle from starting.
Difference between opening and turning on
Opening the car does not mean the security system is validating the key. These are independent functions that can fail separately.
Recommendations:
a) Check the controller battery
b) Use a backup key
c) Avoid impacts to the fob
Frequently Asked Questions:
Can it be reprogrammed?
Yes, in most cases, provided the system allows it.
