Porsche 964 Aftermarket Alarm Retrofit

History
The Porsche 964 came as standard with a factory fitted alarm & immobiliser

The 964's did not have remote central locking. This is the main reason why the original alarm systems were upgraded with Aftermarket systems'. The original system didn't have motion detection within the cabin.

Retrofitting
Many of the upgraded alarm systems retained the original alarm systems in place.


 * Less stripping out
 * Retain the factory immobiliser function
 * Easier to revert back if this is preferred in the future

Arming
The original system was primed when one of the doors is locked with the key.

Retrofit systems will use a keyfob for remote operation

Dis-Arming
The original system was dis-armed when one of the doors is opened with the key.

Retrofit systems will use a keyfob for remote central locking and dis-arming Category:Automotive accessories Category:Automotive companies
