Mitsubishi Endeavor key types & programming facts
The 2004-2012 Mitsubishi Endeavor uses a transponder ignition key plus a separate keyless-entry remote fob. Programming generally involves first registering a working transponder key to the vehicle’s immobilizer through an onboard or diagnostic routine, then pairing the keyless-entry remote to the body control module using a specific sequence of ignition cycles and button presses. Many procedures require at least two already‑programmed keys or specialized locksmith equipment, so customers often need a professional locksmith or Mitsubishi dealer to complete new key or remote setup.
Key types used on the Endeavor:
- transponder chip key (separate metal key plus keyless-entry remote fob) (2004-2012)

How we validate this guide
Year coverage comes from our consolidated vehicle programming dataset. Route-level programming status is reviewed against internal route sheets and available manufacturer, security-access, and professional tool references. Exact button sequences are marked source-verified only when we have year/equipment-specific support; where a year is labeled “route verified, steps vary,” we confirm the exact fob, trim, and prompts before programming. Reviewed for route and safety by Mohammad H. Abdelhadi, ALOA-Certified Master Locksmith.

Common questions
Does my Mitsubishi Endeavor use a separate remote and key or a flip/smart key?
2004-2012 Endeavor models use a traditional metal transponder key with a separate three-button keyless-entry remote fob, not a flip or push-to-start smart key.
Can I program a new remote for my Endeavor myself?
Some 2004-2012 Endeavor remotes can be paired using onboard procedures, but you may need two working keys or professional tools; many owners use a locksmith or dealer for programming.
What battery does the Endeavor key fob use?
Most 2004-2012 Mitsubishi Endeavor key fobs use a CR2032 coin-cell battery, which can be replaced by opening the fob case and swapping the cell.
Can you program a Endeavor key fob without going to the dealership?
For most years, yes - the route is onboard relearn or an OBD tool, both of which a mobile locksmith handles at your location.
Does this program the remote only, or the transponder key too?
It depends on your key type. Tell us your FCC ID and we will confirm.
What if my year says professional programming required?
Those years need a programmer or security access; we bring the tool to you and program it on site.
How much does it cost?
It depends on year, key type, and whether you have a working key. Call (833) 439-8636 for a firm price before we dispatch.
