Everyone who calls a locksmith to get their locks changed or fixed they should be aware that there are at least five different types of deadbolts that locksmiths should readily have available at any time.  So if your are a person who owns a house with wood doors and currently have either kwik set or schlage locksets then you should have your locks upgraded to either Medeco or Mul-T-Locks because the upgrade will enhance the security of the door.  The Medeco and Mul-T-Lock systems have a pick proof cylinders which stop professional thieves from being able to pick your lock open.  The high security deadbolts will also delay your door being kicked in.  To even further enhance the door's security you should have the frame reinforced with a super strike. The super strike is an extended piece of metal which is installed on the frame side of the door.  This is the point where the door latch and deadbolt engage into the frame.  Having an extended piece of metal will stop the wood frame from breaking away while being kicked in.  I recommend fiber glass doors with metal frames as compared to wood doors with wood frames.
In today's economy everyone budgets their money so they can stretch it as far as they can, so when it comes to locks you should also keep your budget in mind and try to get the most for your bucks.  So when it comes to locks your cheapest option is to have your existing locks rekeyed.  Rekeying locks is when the locksmith takes out the existing locks and changes the pins inside the cylinder plugs from the existing to a new key.  The next cheapest option is to install standard quality locks such as Kwik Set locks, Defiant Locks, or Schlage locks.  Okay the next option is mid level locks.  Arrow, falcon, Schlage grade 2 and Master locks.  High Security locks include Medeco, Mul-T-Lock and Abloy locks.  The rekeys should not cost more than $45 per cylinder, regular locks should not be more than $110 each, the mid level locks should not be more than $195 and the High security locks should not be more than $350.  Locksmiths in Queens usually charge less than locksmiths in Manhattan.  All emergency locksmiths are equipped with all the locks I mentioned above.
