"Had a key copied at hardware store but it wouldn't start my car. Royal Locksmith explained about transponder chips, programmed it properly, and now it works perfectly. Should've gone to them first!"
"Lost both key fobs for my Nissan. Dealer wanted $600 and a week wait. Royal Locksmith programmed two new fobs at my house for less than half that price in under an hour. Incredible service!"
