1. Dealership: This is the most expensive option, but also often the most convenient. They can program a new key that will work perfectly with your car's system. Be prepared to show proof of ownership.
2. Locksmith: A reputable locksmith specializing in automotive keys is a good middle ground. They will likely be cheaper than the dealership and can often come to you. Make sure to check reviews beforehand to ensure they are trustworthy and experienced with your vehicle's year and model. They might need your VIN.
3. Auto parts store (like AutoZone, Advance Auto Parts, etc.): Some auto parts stores can cut keys, but for a 2006 Impala with potentially an immobilizer system (which prevents the car from starting unless the key is recognized), you'll likely need a programmed key. Their ability to program will vary by location and may require specific equipment. They might be able to cut a basic key, but you'll still likely need a locksmith or dealership to program it to work.
4. Online retailers (with caution): You can find replacement keys online, but be extremely cautious. Ensure the seller is reputable and understand that you'll likely need to have it programmed by a locksmith or dealership afterwards. Be aware of scams and counterfeits. This is often the cheapest option, but can lead to frustration if the key doesn't work or the programming is difficult.
Important Considerations for a 2006 Impala:
* Immobilizer System: Your 2006 Impala likely has a passive anti-theft system (PATS), meaning the key has a transponder chip that needs to be programmed to your car's computer. A simple key duplication won't work; you'll need a programmed key.
* Key Type: Determine if your key is a standard metal key, a key fob with a remote, or a combination of both. This will influence the cost and process.
* VIN: You'll likely need your Vehicle Identification Number (VIN) to order a key or have it programmed. This is usually found on your vehicle's dashboard, driver's side doorjamb, or your vehicle registration.
In summary: A locksmith is often the best balance of price and convenience. Check reviews thoroughly before committing. Avoid the online option unless you're comfortable with potential complications and are certain of the seller's legitimacy. The dealership is the most expensive but guarantees compatibility and a smooth process.
