Wonder if anyone else is experiencing this. We have an NV200 in the fleet with 66K. Twice, with two different techs assigned to the vehicle, the key is worn down to an unusable state. First time I thought it may be a roughneck using it. We flushed all the locks with WD40 per our locksmith, but then when it happened again, I was stunned. We unlock the doors manually, no remote. There transponder keys are not cheap! Any thoughts? Thanks.
