The 2004 Cadillac DeVille comes equipped with a sophisticated key and key fob system designed for both convenience and security. Understanding how these components work is crucial for optimal vehicle operation and personalization. This guide will clarify the functions of your DeVille’s key fobs and keys.
Key Fob and Key Basics
Your Cadillac DeVille should have been provided with two key fobs upon purchase, helpfully engraved with ‘1’ and ‘2’ on the back for identification. These fobs are the heart of your car’s personalization system. Alongside the fobs, you should also have received three keys: two identical black keys and a gray Valet Key. It’s important to note a mechanical difference: the valet key is designed not to operate the glove box or trunk locks, providing a layer of security when using valet services.
Personalization with Key Fobs
For 2004 Cadillac DeVille models, the keys themselves are not programmed with personal settings. Instead, the key fobs are linked to the car’s personalization system. You can customize your preferred settings, such as seat position and radio presets, using key fob 1, the Driver Information Center (DIC), and door buttons. When you unlock your car using fob 1, the system recognizes it and prepares your saved preferences. Upon inserting your key into the ignition, the car confirms the recognition and applies your personalized settings. The same process applies to fob 2, allowing for different personalization profiles for multiple drivers. You can freely exchange the black keys, as the personalization is tied to the specific key fob used to unlock the vehicle, not the key itself.
Valet Mode Functionality
The gray Valet Key and the valet switch located inside your glove box work in tandem to offer a secure valet mode. To activate valet mode, use a black key to set the valet switch in the glove box, then close and lock the glove box, again using a black key. When valet mode is active, and you provide the valet key to a parking attendant, they will be unable to access the glove box or trunk. Furthermore, the trunk and fuel door buttons are disabled, preventing unauthorized access to these areas.
Key and Fob Programming
If you require replacement keys or fobs, they will need to be programmed to be recognized by your DeVille’s system. The programming procedure can typically be found in your owner’s manual. Alternatively, a Cadillac dealership service representative can assist with programming new keys and fobs. It is believed that the 2004 Cadillac DeVille system can accommodate up to 10 programmed keys. Consult your owner’s manual for detailed instructions on key programming or for any further questions regarding your key fob system.
