My 2017 Hyundai Tucson won't unlock, is it a problem with the key or the car?

Asked by Samantha

Every time I go to use my 2017 Hyundai Tucson, I have to walk at least 100m away from the car with the key then come back to the car for the key to re-register with my car. Is this a fault with the car or the key?

It could be either the car or the remote-control unit at fault, and it’s impossible to tell without actually examining the vehicle. A remote-control unit with a battery that is low on voltage can cause all sorts of mysterious problems with a car’s central locking. But it’s also possible that the vehicle’s body-computer (which controls all the functions involved in unlocking and starting the car) could be malfunctioning also. If that’s the case, it will be a much more involved and expensive job than changing the battery in a remote-control unit.
