About Your 2026 Jeep Cherokee
Jeep is Stellantis' off-road brand and shares its underlying immobilizer platform (Sentry Key SPS) with Chrysler, Dodge, and Ram. Wrangler, Grand Cherokee, Cherokee, Compass, and the resurrected Wagoneer cover most of our Jeep work. The most useful thing to know about Jeep keys: programming requires a security PIN, which we pull on-site from the BCM. Wrangler is a unique case in the Jeep lineup — its key shell is different from Grand Cherokee and the off-road accessories (winch wiring, snorkels) sometimes interfere with the programming session, so we always check before starting. 2018-and-newer Wrangler JL and Grand Cherokee WL/WK use the latest Sentry Key revision and program on-site in 45–60 minutes.
Cherokee KL (2014–2023, discontinued for 2024) uses the basic Sentry Key with model-specific FCC IDs. Latitude and Trailhawk trims share the same fob.
2018-and-newer Jeeps (JL Wrangler, JT Gladiator, WL Grand Cherokee, WS Wagoneer, MP Compass, BU Renegade refresh) use the latest Sentry Key revision with passive entry standard on most trims.
Common issues we see
Wrangler key fobs take more abuse than any other vehicle in our shop — beach trips, mud, water crossings, the works. We see a lot of cracked shells and corroded battery contacts. Most are shell-swap fixes during a normal spare-key visit.
SUVs and crossovers tend to have the proximity Smart Key on higher trims and a basic transponder key on the base trim — we always confirm the exact fob part number before arriving.
Immobilizer (Sentry Key SPS): Stellantis' Sentry Key Plus (SPS) requires a security PIN, which we pull on-site from the vehicle's BCM. Programming is reliable across Chrysler / Dodge / Jeep / Ram.

Frequently asked questions
How much does a Jeep Wrangler key cost?+
Wrangler spare keys start at $149 cut and programmed on-site. All-keys-lost starts at $199. JL (2018+) Wranglers with passive entry are slightly higher.
Can you program a Grand Cherokee smart key on-site?+
Yes. We program every modern Grand Cherokee (WL 2022+, WK2 2011–2021) on-site at your home or work in Jacksonville.
Does the Wagoneer use the same key as Grand Cherokee?+
No. Wagoneer (WS 2022+) has a unique fob shell that's larger than the Grand Cherokee fob. The underlying transponder is the same Sentry Key platform.
