Mitsubishi Key Specialist
Same-Day Service

Yes, for most Mitsubishi models from 2007 through 2024. All-keys-lost on the Outlander, Lancer, Mirage, and Eclipse Cross requires OBD-II access to the immobilizer ECU and a security PIN for post-2000 platforms. We use Autel, Smart Pro, and FVDI2 programmers that retrieve the PIN and register new keys on-site. For older pre-2007 models like the Galant and early Eclipse, the process is even more straightforward using diagnostic tester tools. We confirm the exact procedure from your VIN before coming out.

It depends on the year and model. Mitsubishis built before the late 1990s used standard metal keys with no chip. From roughly 1998 through 2006, most models used transponder chip keys with an integrated or separate remote fob. The Outlander switched to a proximity smart key with push-button start in 2007, and the Lancer followed on higher trims in 2008. The Eclipse Cross and current Outlander all use proximity smart keys. If your Mitsubishi has a Start/Stop button instead of an ignition slot, you have the keyless system.

Mitsubishi dealer pricing runs around $150 for transponder key replacement and $320 for proximity smart keys, with a separate diagnostic fee of $100 to $150 and towing required for all-keys-lost on 2010 and newer models. We handle the blank, cutting, and programming in one on-site visit at a price that is consistently 20 to 30 percent below the dealer total. See the pricing table above for exact figures by key type.

This is a known Mitsubishi Outlander issue. The transponder chip inside the key assembly can physically detach or shift out of position, causing a B1A35 fault code and a key not detected error even with a perfectly good battery. The chip needs to be reseated inside the key housing to restore function. This does not require a new key or reprogramming. If both fobs are failing simultaneously with fresh batteries, the issue is more likely the vehicle's receiver module or antenna rather than the fobs, and we diagnose that distinction on the service call.

Intermittent fob detection on Lancer Evolution models is a documented pattern that is often misdiagnosed as a battery issue. Owners report that even swapping to a brand new battery does not resolve it, and that both fobs fail simultaneously in the same conditions. This points to circuit board wear inside the fob, antenna degradation, or a vehicle-side receiver problem rather than a simple battery failure. Pressing the fob firmly against the start button or door handle reader can sometimes get a read when detection is marginal. We diagnose and address these on-site.

Yes, there is a documented vulnerability in the Outlander PHEV's remote mobile app system. The vehicle's Wi-Fi access point uses a pre-shared key printed in the owner's manual in a format that researchers cracked in under four days using standard equipment. Once connected, an attacker can disable the alarm and control features like climate and charging schedules. Importantly, this vulnerability does not allow the vehicle to be started or driven, and the doors cannot be locked or unlocked through the app connection alone. The mitigation is straightforward: unpair all mobile devices through the app's Cancel VIN Registration option, which puts the Wi-Fi module into sleep mode.

The procedure varies by model. On the 2022 and newer Outlander, hold the back of the dead fob directly against the Start/Stop button while pressing the brake and push the button. On older 2010 to 2021 Outlander models, there is a slot between the dashboard and center console where you insert the fob. On the ASX and RVR, the backup slot is inside the glovebox. On the Lancer, you reconnect the dead fob to the emergency metal blade and insert that assembly into the dashboard ignition slot, then push start. Unlock the door first using the emergency blade in the door handle cylinder, which may trigger the alarm briefly until the car starts.
