Losing your car keys is more than just an inconvenience; it can disrupt your entire day, especially when you rely on your vehicle daily. For owners of a classic like the 1999 Mercedes E320, understanding your key system and replacement options is crucial for peace of mind. This guide will walk you through everything you need to know about 1999 Mercedes E320 Key Fob Replacement, ensuring you’re prepared and never stranded.
The 1999 Mercedes E320 typically comes equipped with a sophisticated key system that includes a key fob for remote locking/unlocking and alarm functions, alongside a mechanical key for manual access. It’s important to differentiate between the types of keys that may have come with your vehicle to understand your replacement needs fully. Your original key set likely included a FOB key, which is the primary remote key, and potentially a flat key (also known as a valet key) designed as a slim spare. The FOB key itself cleverly contains a manual blade key, often referred to as the “valet key,” which can be detached from the fob to manually unlock the door.
If you find yourself in a situation where your 1999 Mercedes E320 key fob is lost or malfunctioning, you have several options for replacement.
Replacement Options for Your 1999 Mercedes E320 Key Fob:
-
Mercedes-Benz Dealership: The most secure but often most expensive option is to go directly to a Mercedes-Benz dealership. They have the equipment to cut and program a new key fob specifically for your vehicle’s VIN. While this ensures compatibility and security, it typically requires proof of ownership and can be pricier than alternatives. The dealership can access Mercedes-Benz’s proprietary systems to order and program a new key that will communicate seamlessly with your E320’s immobilizer and security systems.
-
Specialized Automotive Locksmiths: A more cost-effective alternative is to use a specialized automotive locksmith. Many locksmiths today have invested in advanced key cutting and programming equipment capable of handling European makes like Mercedes-Benz. When choosing a locksmith, verify their experience with Mercedes-Benz vehicles and their ability to program transponder keys and key fobs. A qualified locksmith can often provide a new key fob replacement and programming service at a significantly lower cost than a dealership, and sometimes with greater convenience.
-
DIY Options and Considerations: While true DIY programming of a Mercedes key fob for a 1999 E320 is generally not feasible due to the complex security systems, understanding the components can be helpful. Purchasing blank keys online might seem like a cost-saving measure, but these blanks will still require professional laser cutting and programming to function with your car. Attempting to program a key fob without the correct equipment can lead to security issues or system malfunctions. Therefore, for a 1999 E320, professional cutting and programming are almost always necessary.
Proactive Key Management: Planning Ahead
The best approach to key fob issues is prevention. Consider these proactive steps to avoid being locked out of your 1999 Mercedes E320:
-
Obtain a Spare Manual Key: As highlighted in the original anecdote, getting a spare manual blade key cut is an excellent backup strategy. This mechanical key can be used to unlock your car door if the fob fails or is lost. Keep this spare key in a secure but accessible location, such as your wallet or a hidden spot in a safe place separate from your primary keys. A local locksmith with laser cutting capability can create this spare key relatively inexpensively.
-
Reprogram a Second Fob (If Available): If you have a second key fob that isn’t functioning, explore getting it reprogrammed. As mentioned in the initial story, locksmiths with the right equipment can often reprogram a used fob to work with your vehicle, provided you have at least one working key. This can give you a fully functional spare remote key.
-
Hidden Flat Key: While not advisable to rely on as a primary solution due to security concerns if discovered by the wrong person, the idea of a hidden flat key inside the vehicle, as described, represents an emergency “Plan C.” However, prioritize the security of your vehicle and consider safer alternatives like a spare manual key kept on your person.
Conclusion:
Being prepared for a 1999 Mercedes E320 key fob replacement is about understanding your options and taking proactive steps. Whether you choose a dealership or a qualified locksmith, ensure they have the expertise to handle Mercedes-Benz key systems. Moreover, having a backup plan, such as a spare manual key, can save you considerable trouble and expense in the long run. Don’t wait until you’re facing a lockout – take action now to secure your access and maintain the convenience of your 1999 Mercedes E320.
