Question 1

Are you licensed and insured to work on Ford vehicles in California?

Accepted Answer

Yes. EZ Car Keyz is a California BSIS licensed locksmith company (LCO#6792) and fully insured. You can verify that license through the state bureau directly.

On a 2005 Taurus, the immobilizer work is handled through the OBD port with a programming tool, not through any gated manufacturer portal that requires special credentialing. That said, you still want someone who actually knows this system, not a general handyman with a cheap clone tool. I have been doing Ford transponder work long enough that the 2005 Taurus is a known quantity, not a guess.

Question 2

How do I know EZ Car Keyz is not one of those scam operations?

Accepted Answer

Scam locksmiths are a documented problem, and Ford owners in particular get targeted because key replacement sounds expensive and people panic. The pattern is always the same: no real business name, no verifiable license, a price that doubles after the job starts, and a phone number that goes dead afterward.

EZ Car Keyz has over 100,000 followers across YouTube and TikTok where you can watch this exact type of work being done on camera. I give you a firm price before I drive to you, I show up in a marked van, and the price I quote is the price you pay. The BSIS license number is public record. Look it up.

Question 3

Will the replacement key work exactly like my original?

Accepted Answer

Yes. The blade gets cut to your specific vehicle and the transponder chip gets programmed to your car's immobilizer. Once that's done, it starts the car and holds the registration the same way the original does.

One thing worth knowing: a lot of key blanks sold online are not correctly matched to the 2005 Taurus. The blade may fit the ignition cylinder and the chip may appear to program, but the car rejects it when you try to start it. I stock blanks I have verified for this model year, so that is not a variable you are gambling on when I show up.

Question 4

My 2005 Taurus starts and then immediately stalls. Is that a key problem or something mechanical?

Accepted Answer

That specific symptom, starts for a second then dies, is one of the most common signs the immobilizer is not recognizing the transponder chip. The engine management system allows a brief crank, senses no valid key signal, and cuts fuel. It mimics a fuel or ignition problem well enough that a lot of people go down that road first.

Before you replace a fuel pump or start pulling codes, try a known-good spare key if you have one. If the car runs fine with the spare, the chip in your primary key has either failed or the key's programming dropped out. If neither key works, that points to a deeper immobilizer issue rather than the key itself, and that gets diagnosed on site.

The start-and-stall pattern on this generation is well documented in owner forums. It is almost always the transponder being the culprit when the stall happens within the first two seconds and the car shows a security warning on the dash.

Question 5

I have two keys for my 2005 Taurus. Can I program a third one myself without a tool?

Accepted Answer

Yes, actually. The 2005 Taurus supports an onboard relearn sequence that works when you already have two valid programmed keys in hand. The procedure uses both existing keys in a specific ignition-cycle sequence to put the system into programming mode, then you insert the new cut key to register it. No tool required for that scenario.

If you only have one working key, that onboard path is closed. You need a programmer. Same situation if you are starting from zero keys. Bring what you have when you call so I can tell you which route applies to your car.
