Changing the #FOB battery on a #ToyotaSienna https://youtu.be/K1TdvlaTorU

Bought a 2008 #toyotasienna three years ago, have put on almost 60K miles (now at 217K) and a lot of maint ... but now it needs a transfer case (USD $3K or more) so I'm thinking give up and switch car (prob to a 2016 #toyotahighlander) ... the shopping part is hard, lots of years/options/mileage to compare. Someone should make an #app ...hmmm ...
