Spare Keys Not Working

[akhlaq768]

Brought my Lexus is200 SE (2000) a couple of weeks ago.

Was given 3 sets of keys with it, the main one works and i left the other 2 at home, the mrs today used the spare one, but noticed that none of them worked, the red light doesn't work but the keys do open the door, but then the alarm would go off?

How do i fix this, is it a simple Battery replacement?

hi and welcome to LOC, well as you say the red light doen't come on.would suspect it the Battery,so would suggest you change that first hopefully should be okay thereafter.

is there a special way of replacing these batteries... (like within so many seconds)

And what type of Battery does it take and where can i get them from?

thanks

not sure of the typ of Battery but very easy to change, you need a mini screwdriver to take off the key housing, then you will see the Battery, pop it out and take it to any hardware store and they will give you a new one, cheap as chips

You need a CR1616 battery- get one off eBay. Undo the screw at the back of the key and pop the cover off. Then take the transponder out. There are a further 3 screws on the transponder itself, undo these as well and pop the cover off. Here you will see the Battery. Take the old Battery and re-fit all the items you removed.

sound pretty simple, will get the Battery from eBay...

so there is no time limit or any of those stupid procedure i have to follow, like click key five times... dance around the car and so on?

Dancing around the car doesn't make you a bad man though!!!!!!
