Question 1

Do you use OEM or aftermarket keys on Mitsubishi vehicles?

Accepted Answer

We use OEM spec keys that are verified for your specific Mitsubishi model. Mitsubishis are notoriously selective about key compatibility. A locksmith on Reddit said he only uses OEM or OEM refurbished keys on Mitsubishis because most aftermarket keys fail to function properly. On newer push-to-start Outlanders and Eclipse Cross models, aftermarket smart keys often program the immobilizer but lose proximity range or have dead remote buttons. We match the correct blank, chip, and frequency to your vehicle before we ever head to your location.

Question 2

How long will the replacement key last?

Accepted Answer

A properly programmed Mitsubishi key should last as long as your original. The electronics are the same quality, and the programming does not degrade over time. The most common wear point is the physical shell and blade, which can wear down on remote head keys after years of use. If your shell cracks or the blade wears, a locksmith can often transplant the original electronics into a new case without any reprogramming. One locksmith video showed that as long as you keep the original transponder and board, replacing only the shell does not require a new immobilizer session.

Question 3

What if the new key stops working after a few weeks?

Accepted Answer

Call us. Every key we make is covered under warranty. If the key stops starting the car, loses remote function, or develops any issue, we come back and make it right. This is one of the biggest risks with buying a key online or using a locksmith who does not have the right Mitsubishi tools. One Mirage owner bought an Amazon fob that could start the car but had completely dead lock and unlock buttons. Another Lancer owner ended up with a key that triggered the alarm every time they used it. We test everything before we leave and back it up after.

Question 4

How many buttons does the 2005 Mitsubishi Lancer key have?

Accepted Answer

Your 2005 Mitsubishi Lancer key has 3 buttons. We verify this along with the FCC ID and key profile before we arrive to make sure the key we bring is an exact match for your vehicle. A mismatched fob is one of the most common reasons a cheap key replacement fails. Getting the specs right upfront is how we avoid problems down the line.

Question 5

Can I trust an aftermarket Mitsubishi key to be reliable?

Accepted Answer

It depends on the source and the model. On older Mitsubishis with basic transponder keys like the Galant or early Lancer, quality aftermarket blanks can work but success rates drop to about 50 percent according to one locksmith. On newer push-to-start models like the Outlander, Eclipse Cross, and Mirage with FAST key systems, aftermarket smart keys are a bigger gamble. Buttons may not work, proximity range may be limited, or the key may trigger the alarm. A locksmith on Reddit put it simply: Mitsubishis are quite selective, and most aftermarket keys fail to function properly. We use parts we trust because doing it right the first time costs less than fixing a failed attempt.
