Car key not detected
A key-not-detected message does not identify one definite fault. The fob, its power supply and the vehicle's recognition system need to be considered before a replacement is ordered.
Car key not detected: Investigating the recognition warning
What needs checking
The technician checks when the message appears, whether a spare works and any recent battery, water or impact history.
The work and handover
Testing establishes whether supported fob repair, replacement or programming is appropriate. Vehicle-side faults may need further diagnosis.
Useful details for your enquiry
Give the exact message, make and model, whether the car starts at all and whether another key is recognised.
Car key not detected: questions and answers
Will buying a new fob always solve this warning?
No. The fault may be elsewhere in the vehicle, so a diagnosis helps avoid unnecessary replacement.
What should I bring if I have another key?
Have both keys available and explain which one triggers the message and when it last worked.
What affects the quotation for car key not detected?
Fob testing, vehicle diagnosis and any replacement or programming determine the cost. A quotation should confirm the agreed scope, parts and work before work is arranged.
