Question 1

Are you licensed and insured to work on Acura 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. We are also NASTF Vehicle Security Professional certified, which gives us authorized access to the security and key data needed for vehicles where that access matters.

For a 2004 RSX specifically, this is a Honda-platform car from an era before the newer secure gateway architecture, so the job does not depend on factory portal access the way some later models do. But the credentials still matter -- they tell you the person working on your car went through a vetting process and is not just winging it with a generic tool.

Question 2

How do I know you are not a scam locksmith?

Accepted Answer

Scam locksmiths follow a pattern: a low number quoted on the phone, then a much higher number once they are on-site and you feel stuck. Sometimes a vague "pass or fail" line to cover themselves if the programming does not work.

A legitimate locksmith gives you a firm estimate for your specific vehicle before anyone drives anywhere, explains what the job actually involves, and has reviews you can verify. We have over 100,000 followers across our YouTube and TikTok channels showing real work on real cars. You can watch the process before you ever call.

Question 3

Will the replacement key work exactly like the original?

Accepted Answer

Yes. The replacement is cut to your vehicle and the transponder is enrolled to your immobilizer, so it communicates the same way the factory key did. The car starts, and that is the whole job on this key -- there are no remote functions to test because this is a straight transponder turn-key with no fob attached.

One thing worth knowing: a lot of RSX owners have bought cheap key blanks online and had them cut at a hardware store, only to find the car cranks but will not start. The cut might be right but the chip is either absent, wrong, or unenrolled. We confirm the correct blank and handle enrollment on-site, then start the car in front of you before we leave.

Question 4

I have one working key for my 2004 RSX. Can I add a spare without going to the dealer?

Accepted Answer

Yes, and this is one of the better scenarios to be in. On Honda-family cars of this generation, an onboard add-a-key procedure exists that works through the ignition cylinder when you already have a functional key present. It does not require a trip to the dealer or a diagnostic tool plugged into the OBD port.

The process involves a timed sequence using your existing key, and a new transponder key gets enrolled at the end. I bring the correctly coded blank, cut it to your lock, run the sequence, and you walk away with a working spare. The whole thing typically takes under 20 minutes when a working key is in hand. This is the scenario where getting it done sooner rather than later makes real sense -- add-a-key is easier and faster than all-keys-lost.

Question 5

My 2004 RSX cranks fine but will not start. Could it be the transponder key failing?

Accepted Answer

It can be. On these cars, a transponder that is not being read correctly will let the engine crank but cut the start. The immobilizer blocks fuel or ignition, and the result feels like the engine almost wants to catch but never does.

Check the dashboard for a key-not-detected warning or a blinking security indicator after the crank attempt -- that is a strong sign the transponder is the issue. Worn key heads on older RSX keys are a real thing; the plastic wears, the key body cracks near the blade, and the chip inside can shift or get damaged. If the key looks rough and the car suddenly started doing this, a replacement key is a reasonable first move before chasing anything else.
