Common Issues with 986 Key Fobs

The Porsche 986, encompassing the Boxster and early 996 generation 911, is a fantastic car, but like any vehicle of its era, the key fob can experience issues. These range from simple battery replacements to more complex issues requiring specialized programming. Knowing what to look for can save you time and money.

Dead Battery

Perhaps the most common issue is a dead battery. Symptoms include the key fob not working at all, or intermittently working at close range. This is an easy fix, usually requiring a standard CR2032 battery.

Faulty Micro-switches

Another common culprit is failing micro-switches inside the key fob. These tiny switches control the lock, unlock, and panic buttons. Over time, they can wear out, leading to unresponsive buttons. Replacing these switches is a more involved process, but still achievable for the DIY enthusiast.

Damaged Key Fob Housing

Drops and general wear and tear can damage the key fob housing, potentially affecting the internal components. A cracked housing can expose the circuitry to moisture and dust, leading to further issues.

Programming Issues

Sometimes, a key fob might stop working after a battery replacement or other seemingly unrelated event. This often indicates a programming issue. The fob needs to be re-synchronized with the car’s immobilizer system.

How to Program a Replacement Key Fob for a 986

Programming a new or replacement key fob for a 986 can be done with a dedicated Porsche diagnostic tool, or in some cases, through a specific sequence using the ignition and door locks.

Using a Porsche Diagnostic Tool

The most reliable method is using a Porsche diagnostic tool like the PIWIS tester or a compatible aftermarket tool. This allows for quick and accurate programming of new key fobs.

DIY Programming Method (If Applicable)

Some 986 models allow for DIY programming using a sequence involving the ignition key and door locks. However, this procedure varies depending on the year and model, and isn’t always successful. Refer to your owner’s manual or online forums for specific instructions related to your vehicle.

Key Fob Shell Replacement
