The key should have a small screw located in the plastic cover. Remove it and lift off the cover to reveal a module. Take it out and pull off the case cover. Slide the Battery away from the claws and lift it out. The lithium Battery will have a number on it such as CR2016 and can be bought at most watch repairers or camera shops. Take the Battery with you in case an equivalent one is available.

The change of battery is usually a seamless operation as the key code is not altered. If all else fails the key can be registered using the method below.

Thank you once again Fitter for your reply, I have downloaded your instructions ready incase of a problem, will leave it untill the weather improves as both keys are still working ok apart from the one wich needs the unlock button pressing a couple of times for it to work, but will lock ok & the rear hatch only button works first time, thats why i was thinking it might be the battery getting a bit low & the cold weather might be affecting the battery power

Might be a dodgy contact in the key.

Hi Fitter, thank you for your reply ! I used the following (B. Rewrite mode) but will try your method (which looks nice & quick) with the spare key :

There are four different programming commands when setting up or verifying your remote transmitter, they are:

A. Add mode, used to add a remote to your Prius that is not currently registered.

B. Rewrite mode, used to erase all previously registered remotes and allow you to begin again the programming process.

C. Confirmation mode, used to verify the number of remotes that are already programmed in your Prius.

D. Prohibit mode, to prohibit all remotes from operating the door locks.

All four modes start with these instructions:

1) Make sure that the key is not in the ignition, the doors are unlocked, and the driver's door is open.

2) Very quickly, without turning, insert and remove key from the ignition twice. (leave key out)

3) Close and open the driver door twice. (leave door in open position)

4) Again, insert key into the ignition and remove it. This time only once. (leave key out)

5) Close and open the driver door twice, then close the door.

6) Insert key into the ignition and leave it in the LOCK position.

A. Add mode:

A1) Turn the key to "ON" for 1 second, then turn back to "LOCK".

A2) Remove the key.

A3) You’ll hear the doors "LOCK" and 1 second later "UNLOCK" (just listen)

A4) On your remote, press the lock and unlock buttons simultaneously for 1 to 1½ seconds, then let go.

A5) On your remote, IMMEDIATELY press unlock by itself.

A6) You’ll get one of three responses:

R1) You’ll hear the doors "LOCK", then "UNLOCK" once. The remote is accepted. If you want to program another remote, immediately proceed to step A4 with your second remote, otherwise open the driver’s door and the remote is registered.

R2) You’ll hear the doors "LOCK", then "UNLOCK" twice. Either you didn’t use the same remote in steps A4 and A5(not likely), or this remote was already registered.

The timing was off when you pressed the LOCK and UNLOCK buttons simultaneously and then UNLOCK by itself. Immediately press the two buttons together and the unlock by itself again. Keep trying until you get the locks to signal once that you have been successful. Then if you have another remote to program, quickly press its' buttons as before, until you hear the locks signal once. When you are finished, open and close the driver door to lock in the programming.

R3) If no response, go back to step 1 near the beginning of these instructions.

B. Rewrite mode:

B1) Turn the key to "ON" for 1 second, turn back to "LOCK" for 1 second, then back to "ON" for 1 second, and finally back to "LOCK" for 1 second

B2) Remove the key.

B3) You’ll hear the doors "LOCK", 1 second later "UNLOCK", 1 sec., "LOCK", 1 sec. "UNLOCK". (just listen)

B4) On your remote, press the lock and unlock buttons simultaneously for 1 to 1½ seconds, then let go.

B5) On your remote, IMMEDIATELY press unlock by itself.

B6) You’ll get one of three responses:

R1) You’ll hear the doors "LOCK", then "UNLOCK" once. The remote is accepted. If you want to program another remote, immediately proceed to step B4, otherwise open the driver’s door and the remote is registered.

R2) You’ll hear the doors "LOCK", then "UNLOCK" twice. You didn’t use the same remote in steps B4 and B5(not likely).

R3) If no response, go back to step 1 near the beginning of these instructions.

C. Confirmation mode:

C1) Turn the key in 1 to "ON" and back to "LOCK" in one second intervals for a total of 3 times.

C2) Remove the key.

C3) You’ll hear the doors "LOCK" and "UNLOCK" in 2 second intervals. (just listen and count each set)

1 Set = You have 1 remote registered

2 Sets = You have 2 remotes registered

3 Sets = You have 3 remotes registered

4 Sets = You have 4 remotes registered

5 Sets = You do NOT have any remotes registered

D. Prohibit mode:

D1) Turn the key to "ON" and back to "LOCK" in one second intervals a total of 5 times.

D2) Remove the key.

D3) You’ll hear the doors "LOCK", 1 second later "UNLOCK" 5 times. (just listen and count each set)

D4) This will erase all previously registered remotes and cancel the wireless door lock function.
