The 2003 Acura MDX typically uses a transponder (chip) key that must be programmed to the immobilizer to start the engine. We identify your exact key type, then cut and program a replacement so your vehicle starts, locks, and unlocks the way it should.
We come to you anywhere in Corte Madera: your driveway, a parking lot, work, or roadside. With proof of ownership, we can even make keys when every key is lost.
Dealerships are not your only option for a replacement key. An experienced mobile automotive locksmith often provides the same result — a properly cut and programmed key — with more convenience and, frequently, a friendlier price.

How Acura key replacement works
Confirm the vehicle: We verify your 2003 Acura MDX's exact key type so we bring the right blank and programmer.
Prove ownership: We ask for documentation showing the vehicle is yours — this protects you against theft.
Cut and program: We cut the key and program it to your vehicle's system on location.
Test everything: We confirm the engine starts and that lock, unlock, and remote functions work before we leave.
Where the vehicle supports it, we can also remove previously lost keys from the system during an all-keys-lost job, so an old key that fell into the wrong hands can no longer start your car. Security, not just convenience, is the goal.
2003 Acura MDX key technology
The 2003 Acura MDX generally relies on a transponder (chip) key that must be programmed to the immobilizer to start the engine. That matters because the replacement has to be both cut correctly and programmed to the vehicle — a hardware store copy alone will not start the engine on a chipped or proximity system.
Our mobile unit carries the equipment to handle transponder chip key work for the 2003 Acura MDX in Corte Madera, so you are not stuck waiting on a dealer appointment.
The single best thing you can do to avoid a stressful, expensive day later is to make a spare while you still have a working key. All-keys-lost programming takes more time and costs more than simply cutting a spare — a small step now that saves a lot later.

Avoid a lockout: get a spare Acura key
The single best thing you can do to avoid a stressful, expensive day later is to make a spare while you still have a working key. All-keys-lost programming takes more time and costs more than simply cutting a spare — a small step now that saves a lot later.
A fob that suddenly stops working is not always dead. Sometimes it just needs a fresh battery or a new shell; other times it needs reprogramming. We can test which it is before assuming you need a full replacement.
Acura key replacement cost
Cost depends on the exact key technology your 2003 Acura MDX uses — a basic transponder key is very different from a proximity smart fob — plus whether it is a spare or an all-keys-lost job. Call (408) 755-3415 with your year and model for an accurate quote.
Car key pricing varies more than people expect, because the key itself does. A basic transponder key, a remote head key, and a proximity smart fob are very different pieces of hardware, and programming complexity differs by vehicle too.
An all-keys-lost situation typically costs more than cutting a spare, simply because it requires additional programming. It is one more reason a spare key made today is such a smart, money-saving move.
