2007 Chevrolet Suburban Key Replacement

The 2007–2014 Suburban uses the same key setup, so everything on this page applies to those years too. The full picture is on the Chevrolet Suburban key guide.

2007 Chevrolet Suburban: 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

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 Suburban use?

The 2007 Suburban is a remote-head key vehicle. That means the key blade, the transponder chip and the remote buttons are all built into one plastic head. It is not a push-to-start truck. You turn a real key in a real ignition lock, and the engine will only run if the chip inside the key is recognized by the truck.

The chip is an ID46 transponder, the family GM calls PK3+ (you may see it described as the circle-plus key, and it is a Hitag2-type chip). We pulled that from two separate transponder references, and it is marked verified for this model year. In plain terms: the metal cut gets you into the door and turns the lock, but the chip is what lets the engine start.

There is also a mechanical backup key for this setup. That is useful to know if the remote head has cracked or the battery has died, because the blade can still work the door and ignition path while you sort out the electronics.

Key type: remote-head key with a built-in ID46 (PK3+) transponder
Start system: traditional turn-key ignition, not push-to-start
Programming path: OBD port, no NASTF/SDRM access required

Duplicate key or all keys lost: what is different?

If you still have a working key, making a duplicate is the simpler job. For this Suburban, the original key is needed to clone or add from, and that is the easier situation for both of us. We cut the blade, then program the new chip and remote so the truck accepts it.

If every key is gone, that is still possible on this truck. All-keys-lost is supported for this setup. GM has a timed onboard relearn procedure with three cycles that covers all-keys-lost on most PK3+ vehicles without special tooling. It works, but it takes patience. Programming through the OBD port with a professional tool is faster, and that is the route we prefer when we have the equipment with us.

Either way, we come to you with a mobile van if the Suburban cannot be moved, or you can bring it to our Westwood storefront at 10740 Wilshire Blvd if it still runs and the keys are the only problem.

How we handle a 2007 Suburban key job

The steps below are how a typical job goes. The order changes slightly if you have no working key.

You call (213) 577-1366. We answer around the clock, so a late-night or weekend call is fine.
We confirm the truck by VIN and ask whether you have any working key, a worn key, or none at all.
If the door is locked, we open it without damaging the lock or paint.
We cut the blade to the lock, not just to a worn copy, so it turns smoothly.
We program the ID46 chip and the remote through the OBD port, then test the door, ignition, and remote functions.
We test every key you will be carrying, so you are not left with one that starts the truck and another that only opens the doors.

What affects the cost of a 2007 Suburban key?

We do not quote numbers in a web page, because the real price depends on your situation. Here is what moves it up or down:

Whether you have a working key. Duplicating from an original is usually the more economical route compared with all keys lost.
How many keys you need made and whether the remote buttons are included.
The condition of the original blade and ignition. A worn key or worn ignition wafers can mean extra cutting or lock work.
Where the truck is. A mobile visit differs from bringing the Suburban to the storefront.
The time of day, since we answer at all hours and an after-hours call involves different logistics.
Whether we use the quicker OBD programming or the longer onboard relearn.

What we confirm in person, and why people call us

The chip data for this year is verified, but we still confirm by VIN before cutting or programming anything. Trim, build date and any prior key work can differ from what a reference table suggests, and we would rather check than guess. If anything turns out to need a dealer-only step, we will say so plainly instead of pushing ahead.

Common problems we see on this truck

Three issues come up for this generation. Worn ignition lock wafers on high-mileage Suburbans can make the key stick or refuse to turn. A worn key blade can stop turning the lock even when the chip is perfectly healthy, so a new key is not always a chip problem. And hardware-store copies cut without a transponder will open the doors but will not start the engine. If your spare does that, it needs a transponder chip programmed, or a proper replacement.

Frequently asked questions

Does a 2007 Chevrolet Suburban have a transponder key?

Yes. It uses a remote-head key with an ID46 (PK3+) transponder chip. The truck will not run unless the chip is recognized, even if the blade turns the ignition.

Can you make a key if I lost all my 2007 Suburban keys?

Yes. All keys lost is possible for this setup. We can program through the OBD port with a professional tool, and GM's timed onboard relearn is the slower fallback on most PK3+ vehicles.

Why does my spare key open the doors but not start the Suburban?

It was probably cut without a transponder chip, or the chip was never programmed to the truck. A plain copy matches the lock but cannot pass the engine immobilizer check.

Do I need a dealer for a 2007 Suburban key?

Not for the data we have on this year. Programming is done through the OBD port and does not require NASTF/SDRM access. We still confirm by VIN first, and we will tell you if your truck turns out to be different.

My key turns but feels rough, or will not turn at all. Is that the chip?

Usually not. A worn blade or worn ignition wafers on a high-mileage Suburban are common causes. The chip can be fine while the mechanical side is worn, so we check both.

Should I ask a locksmith for a license?

Yes. California requires locksmith companies to hold a BSIS LCO license, and you can ask any locksmith for it before work begins.
