TPMS not working after tyre change

[Ala Larj]

A couple of weeks ago I had four new tyres fitted at my local Lexus dealer. Since then the display does not show the pressures. I have tried the reset via the contortionist button a couple of times to no avail. Am taking it back to the dealer tomorrow for them to take a look. Does anyone know what the problem could be? I don’t want to be fobbed off by them saying it’s a wear and tear issue not covered by warranty. Thanks.

Batteries in the sensors do not last forever. 8 years is not forever, but most batteries could maybe need to be replaced when that old. I think 10 years would be normal for good quality batteries.

Replacement either from Lexus or https://www.ebay.co.uk/sch/i.html?_from=R40&_trksid=p2380057.m570.l1313&_nkw=tpms+sensor+lexus+gs&_sacat=0

But for all four to fail simultaneously after a tyre change is surely more than coincidental?

I hope they didn’t remove the sensors inside the wheels when doing the tyre change.

Bizarrely they started working on the way to the dealer! Was told that it takes time for them to register a pressure as apparently they monitor rotation and abs. Was also told that the quickest way of resetting them is to drive in a figure of eight for about 10 minutes!
