Question 1

How do I spot a fake locksmith before I get ripped off?

Accepted Answer

A few things stand out. If someone quotes a very low flat rate on the phone and then resets the price once they are standing next to your car, that is a bait-and-switch. It happens constantly with smart key calls because the job sounds simple until suddenly it does not. Search the business name before you call back. No real address, no reviews, stock photo profile, generic name with a city tacked on -- those are all signs. A legitimate locksmith working on a 2017 Outlander should be able to tell you upfront that it is a smart key system, that it needs diagnostic equipment to register, and approximately how long the job takes. If they cannot answer those three things before they arrive, they probably cannot do the job.

Question 2

What exactly is a smart key and why can't I just copy it somewhere?

Accepted Answer

The 2017 Outlander uses a proximity-style smart key with four buttons and a transponder inside the fob body. There is also an emergency blade tucked into the fob that you can pull out manually. The fob communicates wirelessly with the vehicle's security system to authorize starting the engine. It is not a key you can duplicate at a hardware store or a kiosk at the grocery store. Those machines read a metal blade profile. They cannot touch the transponder or register the fob to your car's computer. Any replacement fob has to be programmed through the diagnostic port by someone with the right equipment. The blade portion can be cut on-site. The electronics have to be enrolled. Both have to be done before the key is actually functional.

Question 3

What equipment do you use to program a 2017 Outlander smart key?

Accepted Answer

For this generation Outlander I use professional key programming tools that communicate with the vehicle through the OBD port. The smart key registration process on these requires diagnostic-grade equipment -- not a generic code reader. I also carry the hardware to cut the emergency blade that lives inside the fob. There are forum threads from Outlander owners describing locksmiths who showed up, attempted the job with underpowered tools, failed, and left. That is not a scenario you want when you are already without a working key. Before anyone comes out, it is worth asking whether they have specifically programmed this generation of Outlander smart key before, not just Mitsubishis in general.

Question 4

I have a spare fob I bought online. Can you just program that one instead of selling me a new key?

Accepted Answer

Sometimes, yes. It depends on what you bought. The fob has to match the correct configuration for your vehicle. If the one you have is the right fit and in good condition, I can attempt to register it. Bring it along when I come out and I will check it before assuming we need a new one. If it does not register, we go from there. Buying a fob online is not automatically a problem -- paying someone to program it is always the part that requires a professional either way.

Question 5

My Outlander showed a key warning on the dash and now the push-button start is intermittent. Is the fob dying or is it something else?

Accepted Answer

That warning showing up before the start button goes unreliable is a pattern that comes up with this generation. First thing to check is the CR2032 -- a weak battery produces exactly that symptom, where the system sees the fob inconsistently rather than not at all. Outlander owners on forums describe the car starting fine most mornings and then refusing on a random Tuesday with a key warning, and it turns out the battery was just low enough to cause intermittent handshake failures. Swap the battery first. Use a fresh CR2032 from a sealed pack, not one that has been sitting in a junk drawer. If a new battery does not clear it up, the fob itself may need to be replaced and re-registered. There is also a small chance the issue is on the vehicle side -- an antenna or receiver problem -- but start with the simplest thing before going down that road.
