Jaguar’s key systems evolved from simple transponders to smart proximity fobs with push-to-start, particularly on sedans and SUVs. Dealer key replacements are common but expensive; locksmiths with Jaguar-specific tools can program keys on-site. Frequent replacements involve lost smart fobs, broken flip keys, and battery failures. EV models (I-PACE) use proximity smart fobs exclusively.
