Question 1

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

Accepted Answer

A few red flags to watch before anyone touches your RDX. If they won't give you a real estimate for your specific year and model over the phone, that's a problem. If the quote is some suspiciously low service call fee with "we'll figure it out when we get there," that's a bait and switch. If they say "pass or fail, no guarantee" on programming, walk away. A real locksmith who works on current Acura smart key systems should be able to tell you what tools they use, explain what programming your vehicle requires, and give you a firm price without hesitating. Vague answers on any of those points tell you everything.

Question 2

What exactly is a smart key and why can't I just copy it at a hardware store?

Accepted Answer

The fob your 2024 RDX came with does a lot more than send a radio signal. It carries an encrypted transponder chip that has to be paired to your vehicle's immobilizer. The car won't start without a recognized pairing, no matter what. A hardware store can't do that. An online blank can't do that on its own either. Owners sometimes buy a replacement fob thinking they'll save money on the parts side, then find out they still need professional diagnostic equipment to complete the job. The cutting and the programming are two separate steps, and both have to be done right.

Question 3

What equipment do you actually use to program a 2024 RDX smart key?

Accepted Answer

Professional-grade diagnostic programmers that communicate directly with the immobilizer through the OBD port. These are the same class of tools dealer technicians use, not generic key machines. The 2024 RDX requires tools that support current Honda and Acura immobilizer protocols, and not every locksmith carries that. I've had owners tell me they called around and got turned away because the other shops didn't have compatible equipment for this generation. That's a real thing. If a locksmith can't tell you specifically what tool they're using to program your Acura fob, that's worth asking about before they show up.

Question 4

I lost both keys to my 2024 RDX. Can a new smart key still be made, or is this a dealer-only situation?

Accepted Answer

All-keys-lost on this vehicle is a job I handle on site. It's not a dealer-only situation. The process requires diagnostic equipment to perform a full key memory reset through the OBD port, then register the new fob to the immobilizer. The old fobs get wiped from the system so they can't be used to start the car. It takes longer than adding a spare when you still have a working key, because the reset sequence has a timed step built in. Plan for roughly 45 minutes to an hour. But it gets done in your driveway or wherever you're stranded, same day.

Question 5

My RDX fob works fine for starting the car but the door handle touch unlock stopped responding on the driver side. Is the fob dying?

Accepted Answer

Probably not the fob. If the start button recognizes it and the passenger handle still works, the key is doing its job. Isolated failure on one door handle points to that handle's capacitive sensor or the wiring on that door, not the fob itself. Wipe down the handle area and retest. If it stays isolated to the driver side, that's a door-side diagnosis, not a key replacement job. Worth knowing before anyone tries to sell you a new fob for a problem that isn't coming from the fob.
