2010 Pontiac G6 Key Replacement

2010 G6 key specs

The G6 uses a B111-profile Circle Plus key with a Philips 46 chip, the same key family as the G5 and Torrent. Keyless entry is a separate fob listed under FCC ID KOBGT04A, in 4-button form or with a fifth button for remote start, which was standard on the GT. Catalogs list 4-button fobs under part numbers 22733523 for 2005-2006 and 15252034 for later cars, and a 5-button remote start fob under 22733524, so matching the part number on your old fob matters when ordering.

What's specific to the 2010 G6

2010 was the final model year of the G6 (Epsilon platform). Late-run cars occasionally pick up running changes, so we check the VIN instead of assuming a 2010 Pontiac G6 matches a 2005. A 2010 Pontiac G6 is about 16 years old. Original keys are often worn smooth, and some factory remotes for cars this age are discontinued, so we may suggest a quality aftermarket remote or a separate fob. Because older immobilizers are simpler, all-keys-lost jobs on cars this age are usually more straightforward than on late models.

If a newly cut key turns the 2010 G6's ignition but the engine cranks and dies, the transponder isn't recognized yet; that's a programming step, not a cutting problem, and it's handled at the car.

Key options for the 2010 Pontiac G6

• Transponder (chip) key. There are two ways to give a new transponder key the right identity. Cloning reads the chip in a working key and writes that same ID onto a special cloneable chip, so the car can't tell the two apart. Programming adds a brand-new key ID to the immobilizer's memory through the OBD-II port, sometimes after entering a security PIN tied to the VIN. Cloning is handy when you have a working key and the chip family supports it. Programming is the better choice when keys are lost, because it also lets us remove keys you no longer control from the car's memory. For your Pontiac G6, we'll explain which method fits and why.
• Key with separate remote fob. Pairing a separate remote to a 2010 Pontiac G6 is a different job from programming the ignition key. Some vehicles accept new remotes through an on-board sequence of key turns and button presses; others need a scan tool connected to the OBD-II port. On many of them, entering remote programming mode clears every remote the car already knows, so any remote you want to keep has to be present and re-paired during the same session. Before we start, gather every remote that belongs to the vehicle. Leaving one in a kitchen drawer is a classic way to end up with a remote that quits the day after a new one is added.

How the Pontiac immobilizer works on the G6

Pontiac's last decade covers nearly every theft-deterrent system GM used, plus a few it borrowed from partners. The 2000-2002 Firebird and Trans Am use PASS-Key II, often called VATS: a resistor pellet in the blade has to match the value the car expects. The Grand Am and Sunfire use Passlock, where a sensor in the ignition lock cylinder does the checking and the key carries no chip at all. The Bonneville, Aztek, both Montana vans and every Grand Prix from 2000 through 2008 use PASS-Key 3, or PK3, with a transponder in the key head. Later GM-engineered models such as the G5, G6, Solstice and 2007-2009 Torrent use PK3+, the Circle Plus system with a Philips 46 chip, and so does the Holden-built G8. Then come the outside designs: the Vibe follows Toyota, the GTO came from Holden with its own transponder electronics, and the G3 is a Korean-designed Aveo5. Every Pontiac of this era is a turn-key car, and the brand's final cars were built in 2010.

• Remote start was standard on the G6 GT and optional on base cars, so many fobs carry a fifth start button.
• Coupes and retractable-hardtop convertibles ended with the 2009 model year, leaving the sedan for 2010.
• Catalogs list 4-button KOBGT04A fobs (parts 22733523 and 15252034) and a 5-button remote start fob (part 22733524) for the G6.

Programming a 2010 G6 key

A spare is cut, then learned with GM's on-board add-key sequence using a working key, or with an OBD-II key programmer. All-keys-lost cars need a relearn through the OBD-II port that includes timed security waits before the new key is accepted. Remote and remote-start functions are paired to the body module afterward. We verify ID and registration or title before cutting.

Lost every key to your G6?

1. Gather your documents and the VIN. Call with the year, make, model and VIN if you can read it through the windshield, plus where the car is parked. Those details let us confirm whether your Pontiac G6 can be done on-site and bring the right key, so the first trip is the only trip.
2. Get into the vehicle without damage. If the car is locked, we open it with non-destructive tools such as an inflatable wedge and a long-reach rod, or by picking the door lock. Some vehicles need a careful approach to avoid triggering the alarm, which can interfere with programming later.
3. Originate a new key from the car. With no key to copy, the cuts come from the vehicle itself. We retrieve the key code through manufacturer channels where possible, or decode a door lock with a pick-decoder tool. Then we cut the blade on our code machine and confirm it turns the lock smoothly.
4. Program the key to the immobilizer. Next, the new key is introduced to the car's security system. Many vehicles allow this through the OBD-II port with a PIN or security procedure. Some all-keys-lost cases require reading a module on the bench, and a few platforms only allow dealer programming, which we'll tell you up front.
5. Erase missing keys and add a spare. A lost key's metal blade can still open your doors even after its chip is erased. If the keys disappeared along with something showing where you live or park, consider rekeying the car's door lock cylinders too. We'll also recommend leaving with two working keys, not one.

Why a spare key pays for itself

• Two drivers sharing one key is a daily negotiation. A second key lets a partner, teenager or coworker use the vehicle without handing keys back and forth in parking lots, and it means one person losing their key ring doesn't leave the whole household stuck.
• Electronics fail without warning. A fob dropped on concrete, run through the washing machine or soaked at the pool can quit for good. With a second programmed key, that's an annoyance you fix on your own schedule, not a stranded car that needs attention today.
• When you sell or trade in the vehicle, buyers and dealers expect two keys. A missing key can come up during an appraisal or a private-sale negotiation, so having both on hand keeps the conversation about the car, not about what it will cost the next owner to replace one.

Dealer or mobile locksmith?

Dealers have one clear advantage: direct access to the manufacturer's own systems. Some newer vehicles tie key programming to online authorization that only a dealer can use, and certain all-keys-lost situations on specific platforms still require it. A good locksmith knows where those lines are. Where we can do the job, we use professional programming equipment that talks to the same immobilizer and keyless systems through the OBD-II port, and in many cases the result is identical: a properly registered key that starts the car. Where we can't, we can often still help by opening the vehicle, cutting a mechanical blade from code, or helping you gather what the dealer will ask for so that visit goes smoothly. For your Pontiac G6, ask us directly and you'll get a plain answer.

G6 key battery

A fob battery rarely dies all at once. The warning signs build: you have to get closer to the car before the doors respond, the dash shows a key battery or key-not-detected message, or the push-button start only works with the fob held near the button. Inland heat speeds that decline, especially for fobs left in a hot cabin or on the dashboard. Keep a spare CR2032 at home in a cool drawer, sealed in its original package, and buy from a busy store where stock turns over quickly. A cell that sat on a shelf for years may arrive already partly spent.

How the job works

1. Identify the exact key your G6 uses. We ask a few quick questions on the phone: the year, whether the car starts with a turn key or a button, how many keys you have left, and whether the remote still works the doors. Then we check the VIN against our programming references so the van arrives with the correct blank or fob, not a close guess.
2. Verify ownership before any work. Before cutting or programming, we compare your government photo ID with the vehicle registration or title and check that the VIN on the paperwork matches the VIN on the dash. If the registration is locked inside, we open the car first, confirm the documents, and only then make the key.
3. Get the key code or decode the lock. A key is cut from a code, not a guess. When the factory code can be retrieved through manufacturer channels after ownership is verified, we use it. When it can't, we decode a door lock with a pick-decoder tool that reads the wafer positions without damaging anything, then work out any missing cuts.
4. Cut the blade on-site. Our van carries a code-cutting machine that handles both traditional edge-cut blades and the laser-cut, side-milled profiles common on newer keys. The blade is cut to the code, then test-fitted in a door lock and the ignition or emergency keyhole to confirm smooth operation before any programming begins.
5. Program the chip, remote or smart key. With the blade done, we connect to the OBD-II port and register the new key with the immobilizer. Depending on the Pontiac system, this may involve a security PIN, a timed waiting period, or on-board button sequences for the remote. On some vehicles we clone a working key's chip instead, when that's the more reliable path.
6. Test everything and clear out old keys. The last step is a short walkthrough. We show you how many keys the car now recognizes, point out the dead-fob start method for your vehicle, and hand you an itemized receipt. If a spare makes sense, it's simplest to add it during this same visit while the equipment is already connected.

What affects the price of a G6 key

• The type of key. The biggest factor is technology. A plain mechanical key is a cutting job only. A transponder key adds a chip and programming. Remote-head and flip keys add a circuit board, and a proximity fob for a push-button Pontiac G6 is the most involved of all, both in the part itself and in the programming.
• All keys lost or adding a key. Adding a key while a working one is in hand is the simpler job. With every key gone, we may have to open the car, decode a lock to originate the cuts, and run a longer programming routine, so all-keys-lost work takes more time and costs more.
• Programming complexity and security access. Some immobilizers accept a new key with a few on-board steps. Others need a PIN code, a timed security wait, manufacturer online access, or removing a module to read its data. Every extra layer of security on the Pontiac system adds equipment time and labor to the job.
• Travel, timing and extra repairs. Sometimes a key problem is really a lock problem: an ignition that won't turn even with the right key, or a door cylinder that has been jammed for years. Fixing those is separate work. We point them out, explain the options, and quote the whole job up front so the bill holds no surprises.

Common Pontiac key problems

• A cracked plastic head on a PK3 or Circle Plus key can let the transponder fall out, leaving a key that unlocks the doors but will not start the car. A new learned key is the lasting fix.
• The G5 and Solstice were part of GM's 2014 ignition switch recall, which warned that a heavy key ring could turn the switch out of run. Keep only the car key and fob on the ring.
• Replacement fobs bought online often refuse to pair because the FCC ID or part number differs from the original. Read the back of your old fob before ordering, or let us source the matching one.

Tips from a mobile locksmith

• If your vehicle has a proximity key, think about where it sleeps at night. A fob hanging by the front door can sit within range of relay equipment used to open and start cars from outside. A drawer deeper inside the house, a signal-blocking pouch, or the fob's own sleep mode reduces that risk considerably.
• Learn your car's dead-fob start method now, in the driveway, rather than in a dark parking lot later. Depending on the make, you hold the fob against the start button or place it in a marked pocket in the console. Also find the hidden keyhole on the driver's door handle and practice using the emergency blade.
• Every so often, use the mechanical blade in the driver's door lock. Cylinders that go years without a key can seize from dust and dried grease, and you won't find out until the day the fob dies and the blade is your only way in. A small shot of dry lubricant keeps the lock ready.
