ATS keys & remotes
Keep the remote and the warning together
For your model
The 2019 ATS owner manual describes a transmitter pocket as part of its remote-key guidance. That year-specific backup information should be checked before treating a weak-battery symptom as proof of a failed replacement key.
Before arranging the work
Include the warning text, whether lock buttons still work and whether a second remote starts the car. For a lost remote, report whether any starting transmitter remains.

Key questions
My ATS remote still unlocks the doors. Can it still have a starting problem?
Yes, door-button response alone does not establish successful starting recognition. Describe both results. The 2019 manual provides a backup recognition procedure, and the instructions must match your actual year.
