2003 Honda Pilot Key Replacement

The 2003–2004 Pilot uses the same key setup, so everything on this page applies to those years too. The full picture is on the Honda Pilot key guide.

2003 Honda Pilot: key facts

Key type: Transponder chip key
Push-to-start: No
Transponder chip: Megamos 13
Programming: OBD
All keys lost: We can originate new keys on site

Megamos 13 fixed chip on the HD106 blank; key plus separate remote fob.

What kind of key does a 2003 Honda Pilot use?

The 2003 Pilot is a transponder-key vehicle, not push-to-start. The key has a small chip in the plastic head, and the chip family is Megamos 13, a fixed chip. The blade is the HD106 profile. The remote is a separate fob on the ring, not built into the key head.

What that means for you: the blade has to be cut correctly to turn the ignition and the doors, and the chip has to be programmed to the vehicle before the engine will run. A key that has only the blade cut will turn the lock but the car will not stay running. That is the most common surprise we hear about on this generation of Pilot.

The key also works as a mechanical backup. If the remote fob dies or goes missing, the blade still opens the door and starts the car, provided the chip is programmed. The fob is a convenience, but it is a separate item and is handled separately.

Key type: transponder, no push-to-start
Chip: Megamos 13 (fixed chip), verified
Blank: HD106
Remote: separate fob, not part of the key head

Common problems we see on this Pilot

On a vehicle this age, the trouble usually comes from wear rather than electronics. Three issues come up again and again:

Worn ignition lock wafers on high-mileage cars. The key sticks or stops turning, and a new key alone may not fix it if the ignition itself is tired.
Worn key blades. The chip still works, but the blade has rounded off and no longer turns the locks.
Hardware-store copies cut without a chip. They open the doors but will not start the engine.
A key that sticks or hesitates in the ignition is worth looking at before it breaks off or strands you.

Duplicate key or all keys lost: what is the difference?

If you still have one working key, copying is the more straightforward job. For this Pilot an original key is needed to duplicate from, so we cut the new blade and program the new chip to the vehicle. Working from a good key is usually the more economical route, and it is much better to do it before the last key is gone.

If every key is lost, we can still make you a key. All-keys-lost is possible on this setup. We cut a blade by the lock or by code, then program the new transponder through the OBD port. No special NASTF secure-data registry access is required for this programming method, and we do not need to send you to a dealer for it.

Because we have a storefront and mobile vans, we can do this at your vehicle or at the shop. If the car cannot be driven, the mobile route avoids a tow in many cases.

You call (213) 577-1366 and tell us the vehicle, where it is, and how many keys you have.
We confirm the key setup against the VIN so we cut and program the right parts.
We cut the HD106 blade, by copy from your original or from the lock if all keys are lost.
We program the Megamos 13 chip to the Pilot by OBD.
You test the key in the ignition, the doors, and, if you ordered one, the remote.

What affects the price of a 2003 Pilot key?

We do not quote numbers on a web page because the job itself changes the cost. The main factors for this Pilot are:

Whether you have a working key to copy or all keys are lost. Copying is usually the lighter-cost option.
Whether you need just the transponder key, the remote fob, or both.
Whether we come to you or you come to our Westwood storefront.
The time of day. Late-night and holiday calls are handled by the same people, but they are not the same as a weekday visit.
The ignition condition. If worn wafers are the cause of sticking, the ignition may need work in addition to the key.
How many keys you want made in one visit.

One honest note: we confirm by VIN

The chip data for this model year is verified, but a Pilot is more than ten years old and may have had a previous ignition or key replacement. Aftermarket keys, swapped ignitions, and a different remote can all change what we find. So we confirm by VIN and in person before we cut or program anything. If something does not match what the data says, we tell you plainly rather than guess.

California requires locksmith companies to hold a BSIS LCO license, and you should ask any locksmith for it before they start work, including us.

Frequently asked questions

Does a 2003 Honda Pilot need a chip key?

Yes. It uses a transponder key with a Megamos 13 chip. A plain cut key may open the doors, but the engine will not start without a programmed chip.

Can you make a key if I lost all my 2003 Pilot keys?

Yes. All-keys-lost is possible on this setup. We cut a blade and program the new key by OBD. We confirm the details by VIN first.

Do I need my original key to get a copy?

For duplicating, an original key is needed. If you have no working key, we make one through the all-keys-lost process instead.

Is the remote part of the key?

No. On this Pilot the remote is a separate fob. The key blade with the chip starts the car, and the fob is handled as its own item.

Why does my Pilot key stick in the ignition?

On high-mileage cars, worn ignition lock wafers are a common cause. A worn blade can also cause trouble. We check both the key and the ignition before recommending a fix.

Do I have to go to the dealer?

Not for this model year. Our data shows OBD programming with no NASTF secure-data registry requirement, so we can handle it ourselves.

Can you come to my car?

Yes. We have mobile vans and a storefront in Westwood. Call (213) 577-1366 any time and we will go over where you are and what you have.

We cover all these cities
