Question 1

Are you licensed and insured to work on Porsche vehicles?

Accepted Answer

Yes. EZ Car Keyz holds a California Bureau of Security and Investigative Services license, which is the state-level requirement for automotive locksmith work. We carry full liability insurance on every job.

On a 2003 Porsche 911, key replacement involves reading security data from the immobilizer through the OBD port and programming a new transponder. It's not a job for someone with a generic chip programmer and no documentation trail. You want a licensed tech who can account for what was done, what was programmed, and what the car's security state looks like when they leave. At the value level of one of these cars, credentials matter.

Question 2

How do I know you're not a scam locksmith?

Accepted Answer

Before anyone rolls a truck, ask for their California BSIS license number and get a firm written price for your specific vehicle. If they can't give you a license number or the quote changes when they arrive, send them away.

Porsche key jobs attract inflated quotes. That's real. A price that sounds too good on a 911 key usually means someone is going to show up with the wrong equipment, charge you anyway, and leave without finishing. We quote a firm price on the phone for your year and model, and that number doesn't move when we get there.

Question 3

Will the replacement key work exactly like the original?

Accepted Answer

It should, and we don't leave until it does. On the 2003 911, that means confirming the transponder is properly enrolled with the immobilizer so the engine starts and stays running, and also confirming the remote functions are responding correctly. Both sides get tested on site.

There's a known frustration among 911 owners who bought replacement keys where one function worked and the other didn't, usually because whoever did the job only completed half the programming. We document the work and verify everything before we close up and drive away. If something isn't right, we fix it there.

Question 4

My 2003 911 starts but immediately stalls. Could that be a key or immobilizer issue?

Accepted Answer

Yes, that's a known symptom when the transponder side of the key isn't communicating cleanly with the immobilizer. The engine starts because it gets past the initial crank, then the security system cuts fuel or ignition a second or two later when it doesn't confirm a valid signal.

It can also happen after a battery replacement in the car or a key that's been damaged. The transponder antenna ring around the ignition cylinder is worth checking too. If the ring is cracked or the wiring to it is loose, even a perfectly programmed key will throw this behavior. On this generation 911, that ring sits tight around the ignition and can be disturbed during stereo or dash work. Diagnose before assuming the key itself is the problem.

Question 5

Can I buy a replacement flip key online and have you program it?

Accepted Answer

Sometimes, but it depends on the blank. The 2003 911 flip key has specific requirements for both the blade profile and the transponder chip inside the shell. A lot of aftermarket blanks sold online either have the wrong chip type pre-installed or a blade that looks close but won't cut correctly for this car's locks.

If you want to source your own blank, bring it and I'll tell you on site whether it's workable before any cutting starts. If it's not right, I have blanks. Either way, the programming has to be done by someone with the proper equipment. There's no self-programming sequence for this system.
