2000 Chevrolet Malibu Key Replacement

The 2000–2003 Malibu uses the same key setup, so everything on this page applies to those years too. The full picture is on the Chevrolet Malibu key guide.

2000 Chevrolet Malibu: key facts

Key type: Mechanical (no chip)
Push-to-start: No
Transponder chip: none (Passlock — no chip in key)
Programming: NONE
All keys lost: We can originate new keys on site

Passlock: the security sensor lives in the ignition lock cylinder, not the key — a correctly cut key starts the vehicle with no programming. Security-light no-starts usually mean a failed Passlock sensor, and a 30-minute (3x10-minute) relearn is required after ignition-cylinder or BCM replacement.

What kind of key does a 2000 Malibu use?

The 2000 Malibu has a mechanical key. There is no push-to-start, no remote-head requirement for starting the engine, and no transponder chip inside the key. The data we work from lists the chip family as none, and that is verified against more than one source.

The reason is Passlock. On this system the security sensor sits inside the ignition lock cylinder, not in the key. The car does not need to recognize a coded chip. It needs a key that is cut accurately enough to turn the cylinder and move the wafers the way the factory key would.

For you, that changes the job. Replacing a Malibu key from this year is closer to traditional locksmith work than to electronics work. It comes down to cutting the key correctly and making sure it turns smoothly in both the ignition and the door locks.

Key type: mechanical, cut to the lock
Transponder chip: none (Passlock, nothing in the key)
Push-to-start: no
Programming to start the engine: not needed for a correctly cut key

Duplicate key or all keys lost: what changes?

On this setup, the original key is not required. If you have a working key, we can copy it. If you have lost every key, that is also possible. We can make a key for the car without an original in hand, and because nothing has to be programmed, you are not locked out of the process the way you can be with later chipped vehicles.

Having a key to copy is still the easier route. A copy from a worn key can pass along the wear, so if your existing key already sticks or turns roughly, tell us. We may suggest cutting from the lock rather than from the old blade.

If you are starting from nothing, the work happens at the car. We come to you with a mobile van, or you can bring the car to our Westwood storefront at 10740 Wilshire Blvd if it can be moved. Either way, one company handles it from the first call to the finished key, with no dispatch middlemen.

Why a good key can still leave the Malibu not starting

Not every key problem on this car is a key problem. The commonly reported issues for this year are these:

A failed Passlock sensor in the ignition cylinder: the security light stays on and the engine starts and then dies, even with a good key.
Worn ignition lock wafers on high-mileage cars: the key sticks or will not turn.
Worn or damaged key blades that no longer turn the locks.

Tell us what the car does: no turn, no start, or start and stall.
We check the key blade and how it moves in the ignition and door locks.
If the security light and stall point to the sensor, we tell you the cylinder is the likely cause, not the key.
If the cylinder or the body control module is replaced, the Passlock system needs a timed relearn of about half an hour, run as three 10-minute stages. We do that as part of the repair.

What affects the cost of a 2000 Malibu key?

We do not quote numbers on a web page, because the job decides the cost. For this car the main factors are simple.

A copy from a working key is usually the more economical route. An all-keys-lost situation takes more labor, since the key is made without a pattern. Where we do the work matters too: a mobile call to your location involves travel, while bringing the car to the storefront does not. Time of day plays a part, as we answer 24 hours a day, every day of the year.

The biggest swing is whether the key is really the problem. If the ignition cylinder is worn or the Passlock sensor has failed, a new key will not fix it, and the work becomes cylinder repair or replacement plus the relearn. We will tell you which situation you are in before any work starts, so you are not paying for the wrong fix.

What we confirm in person, and why call us

The key type and chip facts above are verified for this model year. Some details are still worth confirming at the car: the exact blank for your lock, and whether the ignition cylinder has been replaced before, since that can change how the car behaves. We check these by VIN and in person rather than guessing.

Frequently asked questions

Does a 2000 Chevrolet Malibu key have a chip?

No. The 2000 Malibu uses Passlock, where the security sensor is in the ignition lock cylinder. The key is purely mechanical, so a correctly cut key starts the car with no programming.

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

Yes. For this setup an original key is not required, and all-keys-lost replacement is possible. We cut a key to the lock, either at your location with a mobile van or at our Westwood storefront.

Why does my Malibu start and then die with the security light on?

That pattern usually points to a failed Passlock sensor in the ignition lock cylinder, not the key. A new key will not fix it. The cylinder typically needs repair or replacement, followed by a timed relearn.

What is the Passlock relearn after a cylinder replacement?

After an ignition cylinder or body control module replacement, the system needs a timed relearn of about half an hour, run as three 10-minute stages. It is part of finishing the repair correctly.

My Malibu key sticks in the ignition. Is it the key or the car?

It can be either. Worn ignition wafers on high-mileage cars make keys stick or refuse to turn, and a worn blade can do the same. We inspect both before recommending a new key or cylinder work.

How do I know a locksmith is legitimate in California?

California requires locksmith companies to hold a BSIS LCO license. Ask any locksmith for that number before work begins and check it with the state.
