Question 1

Are you licensed and insured to work on Mitsubishi vehicles?

Accepted Answer

Yes. EZ Car Keyz is licensed through the California Bureau of Security and Investigative Services (BSIS License LCO#6792) and carries full insurance coverage. That matters on a vehicle like the 2004 Eclipse because the transponder system requires proper tooling and a working knowledge of how the immobilizer communicates during programming. Not every shop has that, and a botched attempt can lock you out of additional programming attempts. When you call us for your Eclipse in North Park or anywhere else in San Diego, you're getting someone who has done this job before with the right equipment.

Question 2

How do I know you're not one of those bait-and-switch locksmiths?

Accepted Answer

Fair question, and it comes up a lot. The pattern with scam operations is always the same: a low number quoted over the phone, then a drastically different bill once you're already stuck and they've done the work. You'll find complaints about this on local forums and review sites pretty regularly.

Here's what legitimate looks like: a real estimate for your specific vehicle over the phone before anyone shows up, a verifiable business name, actual reviews you can read, and a technician who explains what they're doing. We have over 100,000 followers across our YouTube and TikTok channels where you can watch the actual work being done on real vehicles. You can see how these jobs go before you ever call us.

Question 3

Will the replacement key work exactly like my original?

Accepted Answer

Yes. A properly programmed replacement key for the 2004 Eclipse will communicate with the immobilizer the same way the factory key does. The engine starts, and everything behaves normally. The thing that makes a cheap or improperly done key fail isn't the cutting - it's the programming step. If the transponder isn't enrolled correctly, the car will crank and crank and never fire, or it'll start and immediately stall. I've seen keys that were cut fine but programmed to the wrong parameters, and the owner was convinced the car had a bigger problem.

We test every key before we leave. If the engine runs and holds, the job is done right.

Question 4

My 2004 Eclipse cranks but won't start after I got a new key made somewhere else. What happened?

Accepted Answer

That's almost always a transponder programming failure. The engine cranking means the key is turning the ignition mechanically just fine. The no-start means the immobilizer didn't recognize the chip and cut fuel or spark as designed.

A few things can cause this. The transponder in the new key may not be the correct type for this vehicle. The programming step may have failed partway through and left the key partially enrolled or not enrolled at all. Or the shop used a generic clone without verifying compatibility first.

The fix is re-doing the programming with the right tool and the right key. Depending on how the previous attempt went, the vehicle may need a full re-enrollment of all keys. Call us and we'll sort out where the previous job went wrong before we start.

Question 5

Can I buy a transponder key online and just have you program it?

Accepted Answer

Sometimes, but it's a gamble. The short answer: bring it and I'll tell you if it'll work before I charge you anything to try.

The longer answer is that the aftermarket key market for older Mitsubishis is inconsistent. Some keys sold online carry the correct transponder type for the 2004 Eclipse. Others look identical on the outside and carry a chip that simply won't enroll no matter what tool you throw at it. If the chip type is wrong, no amount of programming time fixes it - you need a different key blank.

If you've already bought one, bring it along when you call. I'd rather check it on the spot than have you pay for a key that won't work.
