I have a friend that has a 2011 ES350. She got an estimate from her stealership of ~$1800 to replace 3 locks on her car that are not working. (Parts alone are $446 per door) I'm looking at aftermarket prices and it seems I can find the front actuators for like $50-$65 or so. Cheapest I can find the back ones for is like $200-$250. Am I looking in the wrong place or is there a legit reason the rear actuators are that much more....even for aftermarket? Anyone know where to find the OE part numbers?

Hope my 6th Gen doesn't develop this issues............seems it was pretty common with the 5th Gen.

Thanks!
