After work intended to address shorter range from a keyless remote, repeat the original conditions in a safe place and check whether the symptom returns. Note whether a spare remote behaves differently and whether the problem began suddenly. Record the result before clearing codes or resetting adaptations.
Follow the maker’s procedure for drive cycles and readiness monitors. Replace the fob battery with the specified type and follow the manual for re-pairing. If the issue remains, return to the evidence instead of swapping another part.
