A deadbolt keyed on both sides is sometimes suggested for doors with glass beside them, but on a main escape door it means finding a key to get out. A door people use to leave the home should open from the inside without a key or special knowledge, especially in an emergency. A single-cylinder deadbolt with a thumb-turn, paired with a reinforced strike and a proper glass film if needed, keeps both security and a clear way out.

Yes, especially on side doors near a treated driveway or walkway. Salt spray dries into a crust inside the keyway and around the plug, and each thaw dissolves and re-deposits it deeper. Over a few winters it pits brass and makes the pins drag. The remedy is a flush with contact cleaner, a thorough drying, and a dry lubricant that sheds moisture, followed by rinsing the hardware when the weather allows.

Yes, at every cylinder that was rekeyed. Once the bottom pins are changed, a key cut to the old combination lifts them to the wrong heights and the plug will not turn. The locksmith proves this at each door by trying the old key after the new one, because any door missed from the list would still answer to the old key. That is also why the walk around the property at the start matters: every door meant to be included has to be on the list.

It depends on what the assessment finds once the locksmith is looking at the actual hardware. A single gate lock that only needs adjusting or rekeying is a shorter visit than one where the closer, hinges and post all need attention, or where several gates on a property are being brought onto one key. Electronic hardware such as a buzzer or electric strike adds its own testing time. The locksmith can give a closer sense of the scope once the gate or door has been examined in person.
