2007 Chevrolet Silverado Key Replacement

The 2007–2013 Silverado uses the same key setup, so everything on this page applies to those years too. The full picture is on the Chevrolet Silverado key guide.

2007 Chevrolet Silverado: key facts

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

Two different trucks were sold as 2007: the new-body GMT900 uses a PK3+ circle-plus ID46 transponder key, while the carry-over 'Silverado Classic' keeps chipless Passlock — we confirm body style/VIN before cutting. 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 2007 Silverado use?

The 2007 model year is awkward, because Chevrolet sold two different trucks under the Silverado name that year. The new-body truck (the GMT900 generation) uses a transponder key with an ID46 chip, the PK3+ "circle-plus" style based on Hitag2. The carry-over truck, sold as the Silverado Classic, keeps the older chipless Passlock system. Those two do not share a key procedure, so the first thing we settle is which one is in your driveway.

For the new-body truck, this is not a push-to-start vehicle. You have a regular key with a plastic head that holds the chip, and a mechanical blade that turns the door locks and the ignition. The blade and the chip do separate jobs. The blade has to match the lock, and the chip has to be recognized by the truck before the engine will run.

That split explains one of the most common complaints we hear. A hardware-store copy cut without a transponder will often open the doors and turn in the ignition, but the engine will not start. The cut is right and the electronics are missing. A key like that can usually be programmed properly only if it is the correct blank with a chip in it, so it is worth checking before you spend anything on more copies.

Spare key or all keys lost: what changes?

For this setup, making a duplicate requires an original working key to start from. If you still have one, adding a spare is the simpler job: we cut a blade and program a new transponder key to the truck.

If every key is gone, that is still possible to solve. All-keys-lost on this generation does not need dealer-only equipment, and no NASTF SDRM access is required. We cut a key from the lock or from the VIN information, then program it to the truck through the OBD port with a professional tool. That route is the faster one.

There is also a slower fallback. GM has an onboard relearn procedure that covers all-keys-lost on most PK3+ vehicles without special tooling. It runs in three timed cycles and takes noticeably longer than OBD programming, so we use it mainly if the tool route is not a fit for a particular truck.

Have one working key: a spare is the simpler job.
No working key: still doable, with cutting and OBD programming done on site or at our shop.
Chip failed but blade is fine, or the reverse: tell us which, since it changes what needs replacing.

How we handle it, step by step

Whether we come to you with a mobile van or you stop by the storefront on Wilshire Blvd, the order is the same.

We confirm the body style and VIN to know whether it is the new-body ID46 truck or the Silverado Classic.
We check what you have: a working key, a worn key, or nothing.
We cut the blade to match the lock, using the correct transponder blank for this truck.
We program the chip through the OBD port and test every key, door lock, and the ignition before we finish.

What affects the price of a 2007 Silverado key?

We will not quote a number on a page, because the honest figure depends on your truck. These are the factors that move it:

Which truck it is. The new-body ID46 truck and the chipless Classic are different jobs.
Spare versus all keys lost. Starting from an existing key is less work than building one from nothing.
Key condition. A worn blade may need a fresh cut from the code instead of a copy of the worn one.
How many keys you want programmed in one visit.
Where you are. A mobile call-out costs more to run than a visit to the storefront.
Ignition wear. If the lock itself is the issue, that is a separate repair from the key.

What we confirm by VIN, and one honest note

Our data for this year is mixed. The ID46 chip family is verified for the new-body truck, but because two trucks were sold as 2007, the details on your specific one are not something we will guess at. We confirm body style and VIN before cutting anything, and if it turns out to be the Classic with Passlock, we will say so and tell you what that involves rather than force the wrong key onto it.

Also, high-mileage trucks often have worn ignition lock wafers. If a key that is cut correctly turns badly or not at all, a new key is not the whole answer. A worn blade can also stop turning the lock even though its chip still works. We can tell the difference when we see the truck.

Frequently asked questions

Does a 2007 Silverado need a transponder key?

The new-body 2007 Silverado does, with an ID46 (PK3+ circle-plus, Hitag2) chip. The older Silverado Classic keeps chipless Passlock. We confirm by VIN which one you have.

Why does my copied key open the door but not start the truck?

A copy cut without a transponder chip can match the lock but cannot be recognized by the truck. The engine will not start until a chip key is programmed to it.

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

Yes. All-keys-lost is possible on this setup. We cut a new key and program it through the OBD port, and no NASTF SDRM access is required.

Do I need my original key to get a duplicate?

Yes, a duplicate starts from an original working key. If you do not have one, we handle it as an all-keys-lost job.

Is this a push-to-start truck?

No. The 2007 Silverado uses a regular key with a mechanical blade for the locks and ignition.

Is the GM onboard relearn something I can do myself?

It exists for most PK3+ vehicles and needs no special tooling, but it runs in three timed cycles and takes much longer than OBD programming. We usually use a pro tool because it is faster.

My key turns hard or will not turn. Is it the key or the ignition?

On high-mileage trucks it can be either. A worn blade can stop turning even though the chip works, and worn ignition lock wafers cause the same symptom. We check both.

We cover all these cities
