Question 1

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

Accepted Answer

Three things to check. First, search the business name against California's BSIS license lookup. Every legitimate locksmith company in the state has a Bureau of Security and Investigative Services license number they can give you over the phone without hesitation. Second, ask for a firm quote for your specific vehicle before anyone drives out. A real tech knows what a 2002 Tiburon key job involves and can give you a number. Vague answers about needing to "see the car first" for a standard key replacement is a stall. Third, check that the person who shows up matches the business on Google. Scam outfits run multiple phone numbers and fake listings that all funnel to the same unmarked van. If the truck has no branding, ask for the BSIS number on the spot.

Question 2

What exactly is a remote head key and what makes it different from a regular car key?

Accepted Answer

A remote head key is a single unit where the remote buttons are molded into the key head itself rather than sitting on a separate fob. Your 2002 Tiburon uses this style. Inside that plastic head is a transponder chip that communicates with the vehicle's immobilizer when you turn the ignition. If the chip is not recognized, the engine either will not start or will start and immediately stall. The remote portion handles lock and unlock functions. Both sides of that key, the transponder and the remote, have to be working and properly matched to the vehicle to get full function. A key that is cut correctly but not programmed will not start the car.

Question 3

What equipment do you use to program a key for a 2002 Hyundai Tiburon?

Accepted Answer

Professional immobilizer programming tools that communicate through the diagnostic port. For a 2002 Tiburon the process is more accessible than on newer Hyundai models, which require additional steps to pull security data before programming can begin. The 2002 is older enough that the job does not involve the locked-down gateway access that later vehicles require. I also carry key blank inventory and cutting equipment in the van, so the blade is cut on site. If a locksmith cannot tell you specifically what tool they are using on your vehicle and why, that is worth a follow-up question.

Question 4

My 2002 Tiburon starts and immediately shuts off. Is that the key or something else?

Accepted Answer

Start-and-stall on this generation points to the immobilizer not recognizing the key. It means the ignition cylinder accepted the blade, but the transponder signal either was not read or was not matched to the vehicle's security system. That can happen with a damaged chip inside the key head, a key that was never properly programmed, or in rarer cases a fault in the immobilizer module itself. Before assuming the module is bad, rule out the key. If you have a second key, try it. If both keys do the same thing, that shifts the diagnosis. I test for this on site before cutting or programming anything new.

Question 5

The lock and unlock buttons on my Tiburon remote head key stopped working. Do I need a whole new key?

Accepted Answer

Not necessarily. The remote portion of a remote head key is separate from the transponder function. If the car still starts normally, the chip is fine. Dead remote buttons are often a battery issue first. Check that before assuming the worst. If a fresh battery does not bring it back, the remote receiver in the vehicle or the key's internal circuitry could be the problem. Either way, you are not automatically looking at a full replacement and reprogramming job just because the buttons stopped responding.
