2008 Chevrolet Malibu Key Replacement

The 2008–2012 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.

2008 Chevrolet Malibu: key facts

Key type: Remote-head key
Push-to-start: No
Transponder chip: ID46 (PK3+ circle-plus, Hitag2)
Programming: OBD
All keys lost: We can originate new keys on site

GM45/B111-family remote-head circle-plus key. GM's 30-minute (3x10-minute) onboard relearn covers all-keys-lost on most PK3+ vehicles without special tooling; OBD programming with a pro tool is faster.

What kind of key does a 2008 Malibu use?

The 2008 Malibu uses a remote-head key. That means the metal blade, the transponder chip and the lock/unlock remote are all built into one piece, and the blade folds into the housing like a flip key. It is not a push-to-start car, so there is no proximity fob to deal with. You turn a key in the ignition.

The chip inside is an ID46 transponder, the family GM calls PK3+ (you may see it described as circle-plus or Hitag2). The car will not start unless the chip in the key is recognized by the vehicle's computer. Cutting the blade alone will open the doors and might even turn the ignition, but the engine will not run without a programmed chip.

The key also has a mechanical backup, so the door can still be opened with the blade if the remote battery dies. That is useful to know: a dead remote does not mean you are locked out.

Key style: remote-head with a flip blade
Chip: ID46, PK3+ circle-plus, Hitag2
Start system: key in the ignition, not push-to-start
Backup: a mechanical blade for the door lock

Duplicate or all keys lost: what changes on this car?

If you still have one working key, duplicating is the simpler job. For this setup an original key is needed to copy from, and we cut a new blade and program a new chip and remote to the car. It is the lighter-cost situation and, in most cases, the quicker one.

If every key is gone, replacement is still possible. All-keys-lost on this Malibu does not require NASTF/SDRM secure-database access, and programming is done through the OBD port. A professional programming tool does it faster. GM also has an onboard relearn procedure that works on most PK3+ vehicles without special tooling, though it is a timed process that runs about half an hour in total. Which route we use depends on the car in front of us.

In both cases we can come to you with a mobile van, or you can bring the car to our Westwood storefront at 10740 Wilshire Blvd. If the car will not start and you have no key, coming to you is usually easier than arranging a tow.

How we handle a 2008 Malibu key job

The steps are short, and none of them involve sending you to a dealer.

You call (213) 577-1366 and tell us whether you have a working key, a broken one or none at all.
We check the VIN and look at the car and any key you have, so we cut and program the right parts.
We cut the blade by code or from your original key, depending on the situation.
We program the ID46 chip and the remote through the OBD port, or use the onboard relearn if that is the sensible route for the car.
You test everything with us there: the door, the ignition, the lock and unlock buttons, and the spare if you ordered one.

Locked out or need a locksmith now?

We answer around the clock, every day of the year.

What affects the price of a 2008 Malibu key?

We do not quote prices on a web page, because the job decides the cost, not the model year alone. These are the things that actually move it:

Whether you have a key to copy or all keys are lost. A copy from a working key is usually the more economical route.
Whether you need only a blade and chip, or a full remote-head with working lock and unlock buttons.
Whether the existing key is merely worn. A cracked shell or broken flip hinge can sometimes be solved with a new shell instead of a whole new key.
How many keys you want made. Programming a spare in the same visit is generally more economical than a second trip.
Where the car is and when you call. A mobile visit and an after-hours call are different from a daytime visit to the storefront.

Common problems, an honest note and why call us

The problems we see on this key are ordinary ones: cracked remote-head shells, broken flip hinges, worn buttons and dead remote batteries. A battery or a shell is often all that is needed, so tell us the symptoms before you assume a new key is required. We also see cloned or low-quality aftermarket chips that work, then fail intermittently. If a key from an online seller or a previous owner starts and stalls unpredictably, the chip is a likely suspect.

On what we are sure of: the ID46 chip family and the OBD programming method for this year are verified against two separate references. Even so, we confirm by VIN and in person before cutting anything, because a previous owner may have swapped in a different key and we want to see what the car actually has. Nothing here is a dealer-only job.

Frequently asked questions

Can you make a 2008 Malibu key if I lost all of them?

Yes. All-keys-lost is possible on this setup, and it does not need NASTF/SDRM access. We program through the OBD port, or use GM's timed onboard relearn when it suits the car. We confirm the details by VIN first.

Do I need my original key to get a copy?

For duplication on this car, yes, an original key is needed to copy from. If you have none, we treat it as all keys lost, which is still doable.

Does the 2008 Malibu have push-to-start?

No. It uses a remote-head flip key turned in the ignition. There is no proximity fob.

What chip is in a 2008 Malibu key?

An ID46 transponder, the PK3+ circle-plus family, also called Hitag2. We still check the VIN and your current key in person, since a past owner may have fitted a different one.

My remote stopped working but the car starts. Do I need a new key?

Not necessarily. A dead remote battery is common. Worn buttons or a cracked shell may also be repairable. If the car starts, the chip is working, and the remote side is often the lighter-cost fix.

Why does my aftermarket key start the car only sometimes?

Low-quality cloned or aftermarket chips can fail intermittently. If that is happening, we can test the key and program a proper replacement.

Do I have to go to a dealer for a 2008 Malibu key?

No. Based on this year's verified data, we handle cutting and programming ourselves, at our storefront or from a mobile van. Call (213) 577-1366 and tell us what you have.

We cover all these cities
