What This Product Does

This genuine Porsche remote communicates with the matching factory central-locking and anti-theft equipment. It is a handheld transmitter, rather than a relay, fixing or vehicle-mounted control module.

Functions

• Transmits locking commands remotely.
• Communicates with compatible factory security equipment.
• Offers controls through two buttons.

Technical Details

• Part identification: 99663724440; two-button configuration; application period 2001–05.
• M534 denotes the anti-theft device. M533 denotes omission of radio-operated convertible-top control.
  
  

Symptoms of Fault

• No response when remote locking is requested.
• Remote operation cuts in and out.
• The transmitter only works close to the vehicle.
• Physical deterioration affects the buttons or casing.
• Manual key operation remains possible while remote operation fails.

Why Replacement Matters

Replacing a confirmed faulty transmitter can recover remote access through the original locking equipment. Similar behaviour may result from a depleted remote battery, low vehicle voltage or faults elsewhere in the security system, so investigate these before changing the transmitter.

FAQs

How many buttons does this version have?
Porsche identifies 99663724440 as having two buttons.

Is every 996 application covered?
No. Check the transmitter-specific dates, body style and M534/M533 requirements as well as the model listing.

Where should intermittent operation be investigated first?
Assess both batteries, inspect relevant connections and review security-system fault information before deciding which component needs renewal.
