Cut, programmed and tested at your car. Most models, most years.

A cut-only duplicate at a hardware kiosk turns the ignition mechanically but has no transponder chip inside — the engine cranks but won't stay running if the immobilizer doesn't see a valid chip signal.
Looks like a normal blade key but has a small chip embedded in the head. Cutting the blade is only half the job — the chip has to be cryptographically learned to the body control module or the vehicle starts and dies within seconds.
A rectangular fob with a slide-out or removable emergency blade. The blade unlocks the door manually but does nothing for the engine — the fob has to be programmed into the SKREEM or RFHM module for both remote functions and start authorization.
No blade inserted anywhere for normal starts — the module reads the fob over RF and the SKIM immobilizer confirms it before the push-button start is allowed to crank. Most have a hidden mechanical blade only for a dead door lock, not for starting the vehicle.
A plain metal blade, a transponder chip, a remote and a proximity fob are four different jobs.
Newer immobilizer generations take extra steps — and on the newest systems, extra authorization.
Copying a working key is the small version of the job; starting from zero keys is the big one.
Secure garages, gated lots and after-midnight calls can change the trip, never the honesty of the quote.
Older Jeeps (mid-2000s through roughly 2010) run the SKREEM (Sentry Key Remote Entry Module) system, which reads a passive transponder chip in the key and won't allow fuel/ignition unless the code matches. From about 2011 onward Jeep shifted to SKIM (Sentry Key Immobilizer Module) paired with the RFHM (Radio Frequency Hub Module) for proximity fobs, which handles both the rolling remote code and the encrypted start authorization. Wrangler held onto a simpler transponder/FOBIK setup longer than the rest of the lineup before the JL generation (2018+) moved to full proximity smart keys. In both systems, a key that isn't taught to the module can be cut or even physically identical and still won't let the vehicle run past a couple seconds.
Losing every Jeep key at once is a harder job than a lockout because there's no working key or fob left to read a code from, so a locksmith has to talk to the SKIM/SKREEM module directly through the OBD port to add a new key from scratch. On many SKIM-based Jeeps (roughly 2011+) that requires either a PIN code pulled from the vehicle's secured data or, on models where the PIN can't be retrieved that way, an all-keys-lost procedure that involves the module accepting a new key only after a timed security delay. Some Grand Cherokee, Renegade, and newer Wrangler JL configurations lock this down tightly enough that the dealer or a locksmith with the right security-gated tool is the only path — a generic key-cutting shop without SKIM access can't finish an all-keys-lost job on those.
Yes, on most Wrangler generations a locksmith with the right SKREEM or SKIM programming tool can cut and code a new key from the VIN and vehicle access alone, though older transponder-era Wranglers and current-generation JL smart keys use different procedures and equipment.
That's the SKREEM or SKIM immobilizer rejecting the key's transponder signal — the mechanical cut is right but the chip inside either isn't programmed to the vehicle or has a dead battery in the fob, so the engine cranks briefly and then shuts off.
It's an all-keys-lost job, which is more involved than a normal lockout because there's no existing key to read a code from. Depending on the model year, a locksmith may retrieve a security PIN from the vehicle's module or need dealer-level access to reset SKIM and program a fresh key.
Largely yes — the Gladiator shares its platform and proximity smart key setup with the JL-generation Wrangler, so fob programming and immobilizer behavior are very similar between the two.
A hardware kiosk can cut the blade shape, but on any Cherokee built with a transponder or FOBIK system that blank still needs to be programmed to the SKIM module before the vehicle will run — cutting alone only gets the mechanical part right.
Dealers can handle it, but they typically require a scheduled appointment and proof of ownership and don't come to the vehicle's location, whereas a mobile locksmith can often cut and program on-site — it's worth asking a locksmith directly whether they support the specific SKIM/SKREEM procedure for that model year before assuming either route.
