Mitsubishi Montero key types & programming facts
2001-2006 Mitsubishi Montero models in the U.S./Canada use a conventional metal key with an immobilizer transponder and a separate keyless-entry remote fob. The remote fob is programmed to the vehicle’s keyless-entry module, while the transponder key must be programmed via the vehicle’s diagnostic/OBD path with appropriate equipment and security access. Replacement remotes must match the correct FCC ID (such as OUCG8D-522M-A or E4EG8D-522M-A) and frequency to operate properly.
Key types used on the Montero:
- transponder chip key (separate remote fob) (2001-2006)
Common fob FCC IDs: OUCG8D-522M-A, E4EG8D-522M-A — check the back of your fob; we confirm the exact variant on site.
About programming your Mitsubishi Montero key
Across the 2001–2006 Mitsubishi Montero model years we cover, key programming is manufacturer-controlled: every year listed above routes to a programmer or security-access procedure rather than an owner-followable onboard sequence. That is normal for this platform — the immobilizer pairs the key’s transponder to the vehicle through an encrypted handshake, so a blank or aftermarket fob will not start the engine until it is properly programmed.
What that means for you: you do not need the dealership. A mobile locksmith brings the programmer to your location, identifies your exact key type and FCC ID from the fob, cuts or sources the correct key if needed, and programs it on site — including all-keys-lost cases where no working key remains.
To program your Montero, have ready: your model year and trim, whether you still have a working key, and the fob itself if you have one (the FCC ID printed on the back identifies the exact key variant). Call (833) 439-8636 and we confirm the route and a firm price before we dispatch.

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
What type of key does a 2001-2006 Mitsubishi Montero use?
It uses a standard metal ignition key with an immobilizer transponder chip and a separate three-button keyless-entry remote fob, not a flip key or proximity smart key.
Which remote will work with my Mitsubishi Montero keyless entry?
Your Montero typically uses a three-button remote with FCC ID OUCG8D-522M-A or E4EG8D-522M-A; the replacement must match the original FCC ID and frequency.
Can I program a replacement remote for my Montero myself?
Some 1998-2006 Montero remotes can be programmed using an in-vehicle procedure, but key transponder programming generally requires a locksmith or dealer using diagnostic equipment.
Can you program a Montero 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.
