Skip to content Car key problems · Brisbane
If your remote will not lock or unlock the car but the key still starts it, the remote side has failed while the transponder is fine. The cause is usually a flat fob battery, worn buttons, or a board or programming issue. A new battery does not fix every remote. Here is what to check and when a mobile locksmith in Brisbane can help.
These are the usual categories, not a diagnosis. The remote is separate from starting the car, so a dead remote does not always mean a dead key.
When another trade may fit: if central locking fails even with a known good remote, the cause can be vehicle wiring or a door actuator, which is auto electrician work. We will tell you if it points that way.
The remote buttons are separate from the transponder that starts the car, so the remote can fail while the key still starts the engine. It is usually a battery, worn buttons, a board fault, or lost sync.
Sometimes, but not always. If the fault is worn buttons or the board inside, a fresh battery will not help. We test it to find the real cause before replacing anything.
Usually yes. A remote has to be coded to the car to operate the locking, so supply and programming go together. We do both on site.
Tell us your make and model and what the buttons do. We test, repair or replace and program on site.
