Try putting the key in the driver's door, lock the vehicle manually by turning the key, remove the key wait a minute or two then reverse the steps and unlock the vehicle, after that try it via the key remote, good luck.

It's not the key, but the car. Basically you have a transmitter (Key) and a receiver (Car).

In order for the system to work, the receiver in the car has to be listening for the signal from the transmitter (Key).

This means that the receiver has to be on, drawing power, even if the key isn't transmitting.

Over time, this will help run down the car battery (the Alarm and some other circuits remain 'live' too, but can't be cut-off), so Porsche has set the receiver to shut off after 120hrs. (5 days) if the Key transmitter hasn't been used.

To reactivate it, you need to unlock the car manually and start the car. If it's not the battery in the Key (Litium CR 2032 3-volt), or some other issue, this should restore normal operation.

Thanks lil bastard and EE3, so your saying lock the car and start it and it should work? Ive been doing that for a couple days and still nothing? or do i have to unlock and lock and start in a specified time? Also it might not be the battery bc the lil red light flashes when i hit it, thanks again for your help guys.

I would still change the battery. The little LED doesn't require near as much juice as the transmitter. You could get the light and still not be able to open the car.

I would try to do the things mentioned in one motion, not wait any specified time.

It is possible that the key is bad, or that something's wrong with either the alarm or the door locks (either mechanical or electric). Have you tried sitting in the car and locking it using the dash button? Does the alarm activate? Do you get the blinking LED on the dash blinking for 10 sec and ten once every 2 sec.? If it blinks for 10 sec and then blinks twice every 2 sec., this indicates a fault in the alarm. The Alarm unit (located under the seat) has a separate API Fuse in it and there is also a fuse in the fusebox on the driver side footwell (#C3 - 15amp).
If swapping the battery checking alarm function LED and fuses don't do it, you'll have to have a dealer look at it with a PST2 or PIWIS diagnostic tool

Oh ok, i was thinking you meant change the car battery and not the key battery, i havent tried that yet and i will at lunch today. When i lock the car it sometimes makes a beeping sound indicating its activated i assume. Also the button on the dash works. Ill let you know if the battery on the key works : ) Do you know what type it is when i go to autozone today?

Lewis,

(Lithium CR 2032 3-volt) flat disc commonly available in drug stores or anywhere with a good stock of batteries. Use care and patience when opening the key, good luck.

Lewis, if the remote has been auto disabled, just locking and unlocking the car door doesnt' do it for me. I have to get in and actually start the car to activate it again as a previous posting member suggested.

Notes:

The car will disable the remote after 5 days of not being used.

The remote is crap and doesn't work nearly as well as my Lexus remote, so don't think you can use it from inside your house or whatever. You must be within ten feet of the car with a fresh battery for it to lock or unlock the doors.
