Wheel refurbish - tyre pressure sensors - hard to remove?

[PJD]

Just on the off-chance someone might be able to offer some help.  I am about to get the wheels refurbished on my 2004 ls430, - however, the garage has advised that the tyre pressure monitors probably haven't been removed since birth so are probably heavily corroded, so, may break when removed.  He also mentioned that there are three different types that he's aware of (his not sure which the LS430 has) - however, some of them are very expensive (£150+VAT - each).

Has anyone here had their wheels done - did you run into problems with the pressure sensors?  Just after any info and wondering how common it is...

I am presuming that if they do break, I could do away with them, and ask Lexus to re-program to turn off the warning lights?

Thanks for any help.

Okay further research seems to suggest that I don't have tyre valve sensors, it simply monitors the circumference of the wheel so shoudn't be an issue
