Does a 2008 HHR have a chip key?

Yes—the 2008 Chevrolet HHR uses a transponder chip in the ignition key as part of its immobilizer system, so a correctly programmed key is typically required to start the vehicle. If you lose the key or need a spare, a dealer or qualified locksmith will usually need your VIN and proof of ownership to code a new key.

What the 2008 HHR key includes

The key is not just a metal blade; it typically combines electronics with a remote and a physical key. Here is what you’re likely to find in this model year:

• Transponder chip embedded in the head of the key


• Mechanical blade for ignition and door locks


• Remote keyless entry fob with lock/unlock, and often trunk release


• Immobilizer system that verifies the key’s code with the vehicle’s computer

In practice, the ignition system reads the embedded chip to authorize starting. A plain, unprogrammed key without the proper transponder won’t start the engine.

How the immobilizer works in the HHR

GM’s immobilizer approach for this era relies on a coded handshake between the key’s transponder and the car’s computer. When you turn the key, the ignition sends a prompt to the chip; if the code is recognized, the engine is allowed to start. If not, the engine stays off and the security light often indicates an issue.

Replacing or adding keys: programming and costs

If you need a spare or replacement, here are your main options and what to expect:

• Dealer or GM-certified locksmith can cut a new key and program the transponder to your HHR using the vehicle’s VIN


• Proof of ownership and the vehicle’s VIN are typically required; some providers may request a photo ID


• Prices vary by location and service; programming usually adds to the cost of the key blade itself


• Some aftermarket options may exist, but compatibility with the 2008 HHR immobilizer is essential and may require professional programming

Bottom line: plan ahead for replacement, and ensure the new key is properly programmed to match the car’s immobilizer.

Troubleshooting common immobilizer/key issues

When the system isn’t recognizing a key or a security indicator is active, these steps cover common scenarios:

• The security/immobilizer light stays on or flashes and the car won’t start


• The engine cranks but does not start, or starts briefly then dies


• A key accepts turning in the ignition but the system doesn’t complete the startup sequence


• The remote fob appears ineffective, which can sometimes relate to separate battery or programming issues

If problems persist, contact a GM dealer or a qualified automotive locksmith with proof of ownership and the vehicle identification number to diagnose and resolve immobilizer or key-related faults.

Summary

The 2008 Chevrolet HHR relies on a chipped, transponder-based key as part of its anti-theft immobilizer system. Replacing or adding keys requires programming by a dealer or qualified locksmith, and issues with key recognition typically point to the immobilizer or transponder rather than the mechanical blade alone. Keep documentation handy and budget for programming costs if you need a spare or replacement key. In most cases, a properly coded key is essential to starting and operating the vehicle.

How do I tell if my key has a chip?

You can tell if a key has a chip by looking for a larger, plastic head on the key, checking if a security light blinks on your dashboard when you start the car, or by trying the "foil test". If the vehicle is newer (manufactured after 1995-1998), it almost certainly uses a transponder key.
 
Physical inspection and simple tests

• Examine the key head: Keys with a transponder chip are typically bulkier at the head, often with a plastic casing, even if there are no remote buttons. 
• Perform the "foil test": Wrap the head of the key in aluminum foil and try to start the car. If the car fails to start, it's likely because the foil is blocking the chip's signal, indicating the key has a chip. 
• Look for a security light: When you insert your original key and turn it to the "on" position, check your car's dashboard. If a security light (often shaped like a key or car) blinks for a few seconds and then goes out, it's a strong indicator that the car uses a transponder system. 

Other indicators

• Vehicle age: If your car was manufactured after 1995 (in Europe) or 1998 (in the USA), it is highly probable that it has a transponder key system. 
• Keyless entry: Keys that have buttons for keyless entry also have a transponder chip, as they are a combined "remote head key". 
• Consult a professional: For absolute certainty, you can ask a professional locksmith or the car's dealership. They can identify your key type using your vehicle's make, model, and year, says American Key Supply. 

How to program a 2008 Chevy HHR key fob?

To program a 2008 HHR key fob, turn the ignition key to the 'On' position, then press and hold the 'Unlock' and 'Lock' buttons on the fob simultaneously until the doors lock and unlock to indicate programming mode. Turn the ignition off, then test the fob to lock and unlock the doors. If this fails, the HHR's remote programming procedure is often complex and may require a dealership scan tool, especially if you have lost all keys.
 
Step-by-step guide

1. Ensure the vehicle is ready for programming: With the ignition off and all doors closed, insert the key into the ignition. 
2. Activate programming mode: Turn the key to the 'On' position. Press and hold the 'Unlock' and 'Lock' buttons on the key fob simultaneously until you hear the doors lock and then unlock. This may take up to 30 seconds. 
3. Finalize the process: Turn the ignition off and remove the key. 
4. Test the fob: Check that the fob now locks and unlocks the doors. 
5. Repeat for other fobs: If programming multiple fobs, repeat the process for each one. 

Troubleshooting and alternative methods

• Replace the battery: If the fob does not work after attempting to program it, replace the battery in the fob. 
• Check for a second working key: If you have a second working key, you may be able to use a different procedure involving inserting both keys into the ignition, turning them on, and then pressing the button on the new fob. However, the procedure described above is the most common starting point for a new fob. 
• Consult a dealership: If the fob still does not program, the vehicle may require a dealership scan tool to complete the process. 
• Lost keys: If all keys are lost, the vehicle will need a new, unprogrammed key to be programmed. This process will erase any previously programmed keys and will require a dealership or automotive locksmith. This can take about 30 to 35 minutes and involves a specific timed procedure. 

What year did Chevy start putting chips in keys?

Chevy started putting transponder chip keys in a more widespread way around 1997, following the earlier and simpler VATS system that began in 1986. While some earlier GM models, like the 1986 Corvette, used a resistor in the key for the VATS system, the true electronic transponder chips for a two-way communication were introduced by General Motors in 1997. The technology then became more mainstream in the 2000s. 

• 1986: GM's Vehicle Anti-Theft System (VATS) is introduced on the Corvette. This system used a simple resistor pellet in the key, not an electronic chip. 
• 1997: GM begins using keys with transponder chips, though they were slow to phase them in across all models. 
• Circa 2005: Transponder chip keys become more common and mainstream across the GM lineup.
