So, you’re the proud owner of a 2005 Infiniti G35 sedan, but maybe you’re not feeling so proud of your key fob situation. Many G35 owners find themselves with only one key, or a key that doesn’t seem to do all the “intelligent” things it should. If you’re scratching your head about getting a new key fob for your Infiniti G35 and trying to avoid those hefty dealership prices, you’re in the right place. Let’s break down your options and get you back to feeling secure and convenient with your car keys.
Decoding Your 2005 Infiniti G35 Key System
It can be confusing trying to understand exactly what kind of key system your 2005 Infiniti G35 sedan has. You might have heard terms like “valet key,” “intelligent key,” or “chip key” thrown around. Let’s clarify what these mean for your G35.
The “intelligent key” system on the 2005 Infiniti G35 is designed for convenience. Ideally, with a working intelligent key fob, you should be able to:
- Unlock the doors and trunk without physically using the key in the lock.
- Start the car with the fob in proximity, often without inserting it into the ignition.
- Potentially utilize other features like panic buttons and remote trunk release.
A “valet key,” on the other hand, is a more basic key. It’s designed to give to parking valets and typically only unlocks the driver’s door and starts the ignition. It usually won’t grant access to the trunk or glove compartment, keeping your valuables secure. Visually, a valet key for a G35 might look like a standard key with a black plastic head, as opposed to a full fob with buttons.
Then there’s the “chip key,” which refers to the transponder chip embedded in many modern car keys. This chip communicates with your car’s immobilizer system. If the car doesn’t recognize the chip, it won’t start, acting as an anti-theft measure. It’s highly likely your 2005 Infiniti G35 key, even a basic looking one, has a chip.
Troubleshooting Common 2005 Infiniti G35 Key Fob Problems
Many 2005 Infiniti G35 owners experience issues with their key fobs. Here are some common problems and potential causes:
-
Limited Functionality: You might have a key that only starts the car but doesn’t unlock doors or the trunk remotely. This could be due to:
- Valet Key: You might indeed have been given only a valet key, which is intentionally limited in function.
- Unprogrammed Fob: Even if you have a fob-style key, it might not be correctly programmed to your car’s intelligent key system.
- System Malfunction: There could be an issue with the car’s intelligent key system receiver or related components.
-
Trunk Access Issues: Having to use the interior trunk release button is inconvenient. This strongly suggests your current key is not a fully functional intelligent key fob or isn’t programmed to operate the trunk release.
-
Fuel Door Concerns: While less directly related to the key fob itself, the fuel door on your 2005 Infiniti G35 is typically a simple push-to-open mechanism, not linked to the intelligent key system. If it’s stuck, it’s likely a separate mechanical issue with the latch or hinge, not your key fob.
2005 Infiniti G35 Key Fob Replacement and Programming: Your Choices
Getting a replacement key fob for your 2005 Infiniti G35 sedan involves a few options, each with different price points and levels of complexity:
-
Dealership (OEM Fob): Going to an Infiniti dealership is the most straightforward but often most expensive route. They can provide a genuine Infiniti key fob, cut the physical key portion, and program it to your car. Expect to pay a premium, potentially $500 or more, for this service.
-
Locksmiths: Automotive locksmiths are often a more affordable alternative to dealerships. Many locksmiths specialize in car keys and key fobs. They can:
- Cut new keys.
- Program OEM or aftermarket fobs.
- Sometimes offer mobile services, coming to your location.
-
Auto Parts Stores & Hardware Stores: Some auto parts stores or hardware chains might offer key cutting and programming services, as you’ve already experienced. However, as you found, their success can be hit-or-miss. They may have limitations in programming certain makes and models or may run out of stock on specific fobs.
-
Online Retailers & DIY Programming: You can purchase aftermarket key fobs online. However, programming can be tricky. Some 2005 Infiniti G35 models might allow for limited DIY programming using specific sequences, but this is not always reliable, and professional programming is often still required. Be cautious with this approach unless you are technically inclined and comfortable troubleshooting.
Considering Aftermarket Remote Start Systems
You mentioned considering a Viper remote start system with a fob. Aftermarket remote start systems like Viper can indeed offer keyless entry and remote start functionality. However, they are generally add-on systems. They typically come with their own separate fobs, rather than replacing your factory Infiniti key fob entirely.
While a Viper system could give you remote locking/unlocking and potentially trunk release, it won’t necessarily integrate with or replace the original intelligent key system functions of your Infiniti G35. You might end up carrying two fobs – the Viper fob and your existing Infiniti key.
In Conclusion
Dealing with key fob issues on your 2005 Infiniti G35 sedan can be frustrating, but understanding your options is the first step to resolution. If you desire full intelligent key functionality, getting a properly programmed fob is key. Weigh the cost and convenience of dealership service against potentially more affordable locksmith or aftermarket options. For reliable results and to ensure compatibility with your car’s system, consulting with a trusted automotive locksmith or your Infiniti dealer is highly recommended.
