Key Remote Control Batteries CR 2032


Recommended Posts

I recently had the need to purchase new CR 2032 Litium batteries for the remote controls on the key, and had to settle for Kodak brand.

Much to my amazement they started to lose their 'punch' after only about a week, and actually would not activate or de-activate the alarm, with very annoying results.

I suppose Duracell are the best, or what else?.

Anyone had any similar exerience with short life lithium cells in the keys ?

I have a 1997 and the remote I use every day still has the original battery. I will have to find the other remote and see if it still works since it has been sitting unused for 5 years.

They say Japanese made batteries for electronic devices are better.

Here is the info from TSB 17/03 9662 Replacing The Key Remote Control Battery (dated 6-25-2004).

This procedure is for the Boxster, Carrera and TT.

Porsche battery part number: 999 611 108 00 Battery For Key Remote

Tools: Flat Screwdriver (small)

Failure of remote control due to replacing battery improperly.

Replacing the battery improperly can cause the processor in the remote control to operate incorrectly so that the remote control no longer functions. For this reason, please inform your customers who purchase a battery for their remote control to not replace the battery themselves.

Replace the battery for the customer as described in the following work procedure to avoid a malfunction of the processor and thus a remote control failure.

- Work Procedure page 2, Step 1, "Replacing the remote-control battery"

After replacing the battery, check if the remote control functions. If the remote control does not function, the processor could have stopped. If this is the case, the LED of the remote control either does not light when the button is pressed or it lights continuously, i.e., longer than length of time the button is pressed. The processor must be restarted.

- Work Procedure page 3, Step 2, "Restarting the processor"

The newly printed editions of the vehicle Owner's Manuals will contain a note that the battery for the remote control should be changed by the Porsche dealer.

1. Replacing the remote-control battery.

1.1 Take a new battery out of the package and set it aside.

1.2 Removing the battery.

Caution!

Damage to the processor due to voltage drops or voltage peaks!

Do not press any button of the remote control directly before replacing the battery and during the replacement.

1.2.1 Carefully lift off the cover of the key head with a finger

nail or a small screwdriver.

1.2.2 Unclip battery on the recess of the top of the battery

(Figure 1) arrow 1) with a finger nail upwards out of

the holder.

1.2.3 Pullout battery from the tab (Figure 1, arrow 2).

Note:

If the remote control does not function after replacing the battery, the processor could have stopped.

The processor must be restarted. In this case, proceed as is described under Step 2.

2.2.3 After a waiting time of approx. 3 seconds, remove this incorrectly polarized battery again.
