If you’re locked out of your house in Boston, don’t worry – stay calm and call Picky Locksmith at 617-665-6928. We offer 24/7 emergency house lockout service. Our nearest mobile locksmith will usually arrive at your residence within 20 minutes. While waiting, if it’s cold or unsafe outside, see if a neighbor can give you shelter. Avoid trying to force the door or break a window – that can cause costly damage. Our professional will get you back inside quickly using non-destructive entry techniques.
It’s not strictly necessary to replace the entire lock, but you should at least rekey your new home’s locks. Rekeying changes the lock so old keys won’t work, and it’s cheaper than full replacement. This ensures former owners or anyone with a spare key can’t enter. We often rekey locks for new homeowners in Boston – it’s a smart security step. If your existing locks are very old or flimsy, then consider a full replacement to a more secure deadbolt. We can advise you on the best option during a quick inspection.
Yes, we install a variety of smart locks, electronic deadbolts, and keyless entry systems for homes. Popular options include keypad deadbolts (where you enter a PIN code) and smart locks that connect to your phone (like August or Schlage smart locks). These systems are great for convenience – no more hiding spare keys under the mat – and you can grant temporary codes to guests or Airbnb renters. During installation, we’ll also ensure the smart lock is properly calibrated to your door. If you’re interested, we can recommend models that fit your door and budget.
