Having trouble with your 1999 Mercedes-Benz E320 key fob? You’re not alone. Key fobs from this era can be finicky, leaving you stranded with a car that won’t unlock or start. This guide will walk you through everything you need to know about 1999 E320 Key Fob Repair, from common problems to troubleshooting solutions and replacement options.
Common 1999 E320 Key Fob Issues
Before we dive into repairs, let’s look at the typical culprits behind key fob malfunctions:
- Dead Battery: This is the most common reason your key fob might stop working. Batteries naturally deplete over time, and a dead battery means your car can’t receive the signal from the fob.
- Worn-Out Buttons: Years of pressing those unlock and lock buttons can take their toll. Over time, the buttons can wear out, making them unresponsive or sending intermittent signals.
- Faulty Programming: Sometimes, the issue isn’t with the key fob itself but with its programming. If the fob’s signal isn’t properly synced with your car’s receiver, it won’t be recognized.
- Internal Damage: Moisture, impact, or general wear and tear can damage the key fob’s internal components, such as the circuit board or antenna. This damage can disrupt the fob’s ability to function correctly.
Troubleshooting Your 1999 E320 Key Fob
Here are some troubleshooting steps to try before heading to a mechanic:
- Replace the Battery: This is the easiest and cheapest fix. Pop open your key fob and replace the battery with a fresh one, making sure it’s the correct type.
- Reprogram the Key Fob: You might be able to reprogram the fob yourself using your car’s owner’s manual. However, this process can be tricky, and you might need to visit a dealership or specialized locksmith.
- Inspect for Physical Damage: Check your key fob for cracks, loose buttons, or water damage. If you find any significant damage, it’s best to replace the fob.
When to Seek Professional Help
While some key fob issues can be resolved with DIY solutions, others require professional assistance. If you’ve tried troubleshooting and still face problems, it’s time to contact a qualified mechanic or locksmith specializing in Mercedes-Benz vehicles. They have the expertise and tools to diagnose and fix complex issues, including:
- Replacing faulty internal components
- Repairing or replacing damaged key fob casings
- Reprogramming key fobs with specialized equipment
1999 E320 Key Fob Replacement
If your key fob is beyond repair or you need an extra one, here are your replacement options:
- Dealership: You can purchase a new OEM (Original Equipment Manufacturer) key fob from a Mercedes-Benz dealership. While dealerships offer genuine parts and programming services, this option is often the most expensive.
- Automotive Locksmith: Many automotive locksmiths specialize in key fob replacements for various car models, including Mercedes-Benz. They can often provide more affordable options than dealerships, but always ensure they use high-quality fobs and programming equipment.

Here are a few tips to keep your key fob functioning smoothly:
- Replace the Battery Regularly: Don’t wait for your battery to die completely. Replace it every year or two as a preventative measure.
- Protect Your Key Fob: Invest in a protective case or keychain to shield your fob from impacts, scratches, and moisture.
- Keep it Away from Extreme Temperatures: Extreme heat or cold can damage your key fob’s battery and internal components.
