2000 Honda Odyssey Key Replacement

The 2000–2004 Odyssey uses the same key setup, so everything on this page applies to those years too. The full picture is on the Honda Odyssey key guide.

2000 Honda Odyssey: 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. All-keys-lost is usually OBD-doable, but the earliest immobilizer units can need bench or dealer work.

What kind of key does a 2000 Honda Odyssey use?

The 2000 Odyssey uses a transponder key. It is a standard metal-blade key with a chip sealed in the plastic head. The chip family is Megamos 13, a fixed-code chip, and the blade is the HD106 type. There is no push-to-start system on this year, so you are dealing with a key that goes into the ignition cylinder and turns.

That setup means two separate things have to be right for the van to run. The blade has to be cut correctly to turn the ignition and the door locks, and the chip has to be programmed so the immobilizer recognizes it. The key also works as a mechanical backup for the locks, so a key with a dead or missing chip can still open a door and even turn the ignition, but the engine will not stay running.

This is why a hardware-store copy so often disappoints. It is cut to the right shape, it opens the doors, and it may turn in the ignition, but without a programmed chip the engine will not start. If you were handed a cheap copy and the van will not run, that is almost certainly the reason.

Duplicate key or all keys lost: what changes?

If you still have one working key, a duplicate is the simpler job. For this year the original key is needed to make the copy, and we cut the blade and program the new chip to the van. Having a spare made before the last key disappears is the more economical route by a wide margin.

If every key is gone, replacement is still possible. For this vehicle, all-keys-lost work can usually be done through the OBD port under the dash, without towing the van anywhere. We cut a blade to the lock, then program a new key to the immobilizer. Where the lock has to be read and cut from scratch, that adds labor, which is a normal part of an all-keys-lost job.

One key in hand: we copy the blade, then program the chip to the van.
No keys: we cut a new blade to the lock and program through the OBD port in most cases.
Key opens the doors but the engine will not start: the chip is missing, wrong, or not programmed.

What we do, step by step

Here is how a typical 2000 Odyssey key job goes, whether we come to you in a mobile van or you stop by the Westwood storefront.

Confirm the van, the year, and that you are the owner, because we ask for proof of ownership before making keys.
Check the ignition and the existing key. A worn blade or a sticking ignition is better caught before cutting a new key.
Cut the HD106 blade by code or from the original key, or read the lock if no key is available.
Program the Megamos 13 chip to the van through the OBD port.
Test the key in the ignition, the driver door, and the other locks before we leave.

Wear problems we see on these vans

On a high-mileage Odyssey, worn parts cause as many calls as lost keys do. These are the problems that come up most often with this year:

Worn ignition lock wafers: the key sticks, or it stops turning in the ignition. A brand-new key will not fix a worn cylinder, so we look at the lock first.
Worn key blades: the chip still works, but the blade no longer turns the locks well. A fresh blade cut to the code often solves it.
Chipless hardware-store copies: they open the doors but will not start the engine, as covered above.

What affects the price of a 2000 Odyssey key?

We do not quote numbers on a web page, because the real figure depends on your situation. These factors move the cost up or down:

Duplicate versus all keys lost. Having an original key to copy is the lighter-cost route.
Whether the ignition cylinder is worn and needs work before a new key will behave.
How many keys you want made at the same time.
Where you are and when you call, since mobile service involves travel and after-hours work.
Whether the immobilizer unit turns out to be one of the early ones that needs extra work (see the next section).

What we confirm in person

Our data on this year is verified: Megamos 13 fixed chip, HD106 blank, OBD programming. There is one honest caveat. The earliest immobilizer units can need bench or dealer work in an all-keys-lost situation. We cannot tell from a description which kind your van has, so we confirm by VIN and by looking at the van itself before committing to a plan. If your van turns out to need that extra step, we will tell you plainly instead of starting a job we cannot finish.

Frequently asked questions

Does a 2000 Honda Odyssey have a chip in the key?

Yes. It uses a transponder key with a fixed Megamos 13 chip on an HD106 blank. The key has to be cut correctly and the chip programmed to the van, or the engine will not run.

Why does my copied key open the doors but not start the van?

Most likely it was cut without a chip, or the chip was never programmed. A chipless copy can open the locks, but the immobilizer will not let the engine run.

Can you make a key if I lost all of mine?

Usually yes. All-keys-lost work on this year can generally be done through the OBD port. The earliest immobilizer units can need bench or dealer work, so we confirm by VIN and in person.

Do I need my original key to get a copy?

For a duplicate, yes, the original key is needed. Without one, we treat it as an all-keys-lost job, which takes more labor.

My key sticks or will not turn in the ignition. Is it the key?

It can be the key or the ignition. Worn lock wafers on high-mileage vans cause sticking, and worn key blades cause the same symptom. We check both before cutting anything new.

Is this a push-to-start vehicle?

No. The 2000 Odyssey uses a regular key that goes into the ignition cylinder. There is no push-button start.

We cover all these cities
