Mitsubishi Key Replacement Service in Houston, TX
Modern Mitsubishi vehicles rely on an immobilizer system that won't let the engine start unless it recognizes a properly coded key. That means a Mitsubishi key is rarely just a piece of cut metal: there's a transponder chip, a remote, or a full proximity smart key that has to be matched to your vehicle's security data. Texan Locksmith handles all of it on-site. We cut the physical blade when needed and complete the programming so the new key actually starts the vehicle.
Because we bring the equipment to you, you can often skip the tow bill and the dealership scheduling backlog. Many customers pay noticeably less than a dealer quote for a comparable key, though the exact difference depends on the model, key type, and parts availability. Whichever route makes sense for your vehicle, we tell you the price up front before any cutting or programming begins.

Mitsubishi Key Replacement FAQ
How much does a Mitsubishi key replacement cost in Houston?▾
Most Mitsubishi key replacements in the Houston area typically fall between $120 and $400, depending on the model, the key type, and parts availability. Basic transponder keys usually sit toward the lower end of that range, while proximity smart keys tend to land higher because the fob hardware and programming are more involved. All-keys-lost situations often cost more, since additional security steps and full vehicle pairing are required. You get an exact quote up front before any work begins.
Can you program a key if all of my keys are lost?▾
Yes, in most cases we can create and program a new key even when no working key is left. Because this is an all-keys-lost situation, we'll ask for a valid photo ID and proof of ownership before we begin. Whether it can be completed fully on-site is year and immobilizer system dependent, so we'll confirm the specifics for your Mitsubishi when you call.
How long does it take?▾
Most Mitsubishi key replacements are completed in a single visit once we arrive, including cutting, programming, and testing. Simple duplicate keys are usually the quickest, while all-keys-lost situations and certain smart key systems take longer because extra security steps are involved. Timing varies by model, key type, and the work required, and we walk you through what to expect before we start.
Can you just replace the key fob battery, or is it something deeper?▾
Often a remote or smart key that's acting up just needs a fresh battery, and that's a fast, inexpensive fix we're happy to handle. If a new battery doesn't solve it, the issue may be a worn fob, a programming problem, or an immobilizer fault, so we can run a deeper diagnosis on-site to pinpoint the cause and recommend the right repair or replacement.
If you're standing next to your Mitsubishi and the keys are locked inside, you don't need a new key at all — you need emergency car lockout service. We open the door on-site, and if the key turns out to be lost rather than locked in, we cut a replacement in the same visit. Run Mitsubishi vans or trucks for work? We also handle commercial locksmith work for Houston businesses, from fleet keys to office master key systems.
