Porsche Parts needed: 

993-618-959-12 (Hand Remote Housing) Click for Price

944-538-041-00 (Lighted Key Cap) Click for Price

Optional: replacement remote battery

Tools needed:

Small Phillips screwdriver (#0 or #1)

Very small slotted screwdriver (eyeglass screw size)

Time: 15 minutes or less

1.....Dissasemble old remote housing by removing small Phillips screw from bottom of unit. Open case and carefully remove circuit board with the battery. If the battery is old, this is a good time to replace it.

2.....Insert circuit board into new remote housing. It is a tight fit, but should not require much force. The battery goes in the fat end. The board has a top (component side) and a bottom (flat) - make sure the top of the board mates with the upper half of the new housing (the half with the rubber push button). Close the housing by snapping it together and inserting/tightening the Phillips screw supplied with the new housing.

3.....Push the switchblade button to expose the key. Remove the key from the switchblade housing by using the small screwdriver to remove the cap (see attached excerpt from the factory shop manual) by prying gently from the end farthest from the key. The cap comes out almost perpendicular to the unit. After removing the cap, remove the small spring which should now be exposed. Push the key straight into the end of the housing and tap it gently on the end while holding the unit with the key up. With a few taps and jiggling the locking slide should be released and the key may be easily pulled out of the housing.

4.....Insert the key into the Lighted Key Cap. Note: the key has two prongs and the key cap has two slots. On the key one prong is straight and the other is notched. The notched key prong goes into the key cap slot that has a visible "catch" in it. Push the key in until it catches.

5.....Attach your new remote housing to the key cap with the provided ring and you are done. Pat yourself on the back and rejoice in your accomplishment. Soon you will be ready to move on to reprogramming the ECU.
