Question 1

What is the cheapest way to replace a lost key for a 2008 Mitsubishi Lancer?

Accepted Answer

Call a mobile locksmith first. The dealer is going to separate out the fob, the blade, the programming, and the labor into individual line items. By the time that invoice is done, you've also arranged a tow if the car isn't drivable and waited several days for an appointment slot.

With EZ Car Keyz, I come to you in Chula Vista or Bonita, do the programming on site with my own equipment, and hand you a working key before I leave. No tow, no appointment, no per-item billing. You get pricing when you call, but the comparison to the dealer is not close.

Question 2

How much more complicated is all-keys-lost compared to just adding a spare?

Accepted Answer

Significantly more involved. When you still have one working key, adding a spare is a registration job. The system already has a valid key enrolled, so you're just telling it to accept one more.

All-keys-lost means the immobilizer memory has to be fully cleared and reinitialized before any new key can be registered. On the 2008 Lancer, that requires the right diagnostic equipment and the correct access procedure through the OBD port. It takes longer, it costs more, and if you're doing it after a theft, you also want to confirm the old fobs are gone from memory so they can't be used.

The smartest move is getting a spare made while you still have a working key. It is a shorter job, a simpler process, and it costs less. Waiting until you're in an all-keys-lost situation is the expensive version of the same outcome.

Question 3

Are aftermarket Mitsubishi fobs cheaper and do they actually work?

Accepted Answer

Cheaper upfront, yes. Reliable, not consistently. The 2008 Lancer is one of those vehicles where the fob hardware has to be a close match for the programming to take cleanly. Forum threads on Mitsubishi owner communities have multiple reports of cheap aftermarket fobs that partially program, meaning the car starts but the central locking misbehaves, or the alarm triggers on unlock, or range drops to a few feet.

One pattern that comes up repeatedly: the fob pairs to the immobilizer but the remote functions never sync correctly. The owner gets a key that starts the car and nothing else. That's a frustrating outcome when you paid for a full replacement.

I carry fobs verified to work with this vehicle. It costs more than a $15 shell from a marketplace site, but you're not gambling on whether it'll actually function when the job is done.

Question 4

My 2008 Lancer starts fine but the remote lock and unlock buttons stopped working. Is the fob dead?

Accepted Answer

Not necessarily. On this generation Lancer, the remote functions and the immobilizer/start function are handled separately. So a fob that lost its remote pairing can still start the car just fine.

First thing to check is the CR2032 battery. A weak cell can drop the radio signal before it affects anything else. Swap the battery and retest from different distances.

If a fresh battery doesn't bring it back, the remote side may have lost its registration, which can happen after a battery goes completely dead or after certain electrical events on the car. That's a re-pairing job, not a full key replacement. Worth diagnosing before assuming you need new hardware.

Question 5

Can I program a second key for my 2008 Lancer myself, or do I need a professional?

Accepted Answer

You need equipment. There is no owner-accessible button sequence or ignition-turn procedure for adding a smart key on this vehicle. That self-programming approach exists on some older Mitsubishi models with basic transponder keys, but the 2008 Lancer smart key system requires the new fob to be enrolled through the diagnostic port with the right software.

If you bought a fob online already, hold onto it. It may still be usable. Bring it when you call and I can confirm whether the hardware is compatible before starting the job.
