Bought a new Boxster S and key remote wont work?

[BoxsterLewis]

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.

When the car goes into "power save" mode or "sleep" mode as Lil Bastard described, you must start the car (after unlocking with the key) within a very specific amount of time (< 60 seconds) or else the alarm will sound and activate.

Yah the alarm has gone off on me a couple times already. The only way to get in is using the actual key and starting the car so ive done this several times with no luck, must be the key battery...

K its not the key battery, just bought 2 at the drug store and unlocked the car and turned it on and nothing happens when i hit the buttons. They do flash differently now i think, like one button flashed fast 4x then pauses and another button does something diff..weird?

Ok, I think I may know what's going on. I believe the key is in lockdown.

If the transmitter on the key is operated more than 256 times beyond the range of the car, or with the car stored w/ battery removed, the next time the key is operated, the car won't recognize it.

This can occur if someone is 'playing' with the key, or if the key is being accidentally activated, say in someone's pocket, unbeknownst to the owner.

If this is the case, the procedure is:

• Switch ON the ignition with the key
  
  Switch OFF ignition
  
  Remove key from ignition
  
  Press transmitter within 6 sec. of removing it

That should reset it, unless the key has been operated 1024 times or more in which case, only the dealer can reset it. Performing this procedure resets this function to zero.

I have no idea why such a function should exist. Perhaps it's a safeguard should someone find the key and try walking through a neighborhood or parking lot trying to get a car to respond to it. Unlucky you if the thief finds the car on the 255th try I guess...
