Installed on Friday and worked Friday and Saturday. Had taken my truck for a longer drive and got a tire pressure sensor error message on all four wheels! Terrible! Didn't even work for a week! UPDATE May 10th: Today one of them accidentally started working again. didn't even have these things for two weeks. what a mess. Run away from them as far as possible and stick to the OEM sensors! Last update May 12th: Now the second sensor is working again. not even owned these things for 11 days. I tried reprogramming them at a tire shop and they still work! Waste of money and time!
