Dead battery in smart key

[dpcompt]

I have owned a lot of cars with smart keys over the years and the batteries that died usually lasted well past a year. My wife's Landcruiser smart key quit after a month. I ordered some batteries from Amazon and will replace the one in her smart key. The other key is working. Has anyone experienced this problem in their new Landcruiser?

The same thing happened to me, had to order new batteries from Amazon and then thought that the battery couldn't have been empty after just a month of ownership. I opened the smart key case, removed the battery, let it set for about 30 seconds, and then reinstalled the battery. Sure enough, the reboot of the key got it working again.

I now have spare batteries sitting at home when the factory batteries need to be replaced.

When I was in the stealership yesterday, I told them that it was ridiculous that I had to hold the key fob right up to the door handle. They replaced my battery with a complementary replacement and it seems to be working better now. This battery is supposed to last 2 to 3 years, but six months is ridiculous.

Mine died after 2 months! I've luckily been using the spare but will try to remove and replace to see if that works!
