Some rotary combination locks in Palm Beach can be manipulated by feel or sound in order to determine the combination required to open the safe. More sophisticated locks in Palm Beach use wheels made from lightweight materials which reduces this vulnerability. Another anti-manipulation mechanism is serrated wheels (false tumbler notches) that make tactile techniques much more difficult. Another defense is a clutch-type driver wheel that prevents contact of the fence to the tumblers except in one position. These locks can be identified by a "click-click" feeling in the dial or by a dial that is pushed in and turned. Manipulation is the locksmith's preferred choice in lost-combination lockouts, since it requires no repairs or damage, but can be extremely time consuming due to lock improvements over the years, and is also a difficult art to master. Some combination padlocks in Palm Beach can also be manipulated by pulling and applying leverage on the shackle while turning each dial to determine the combination required to unlock them.
In the absence of any other information regarding the safe's combination, a combination lock in Palm Beach may be opened by dialing every possible combination. Locksmiths in Palm Beach discovered that many combination locks allow some "slop" in the settings of the dial, so that for a given safe it may be necessary only to try a subset of the combinations. This drastically reduces the time required to exhaust the number of meaningful combinations. A further reduction in solving time is obtained by trying all possible settings for the last wheel for a given setting of the first wheels before nudging the next-to-last wheel to its next meaningful setting, instead of zeroing the lock each time with a number of turns in one direction.
While most safes in Palm Beach are hard to open, most are susceptible to compromise by drilling or other physical methods. Manufacturers publish drill-point diagrams for specific models of safe. These are tightly guarded by both the manufacturers and locksmithing professionals in Palm Beach. Drilling is usually aimed at gaining access to the safe by observation or bypass of the locking mechanism. Drilling is the most common method used by locksmiths in Palm Beach, and is the only method that can be used in cases of burglary attempts, malfunctioning locks or damaged locks. In observational attacks, the drill hole allows the safecracker to view the internal state of the combination lock. Drill-points are often located close to the axis of the dial on the combination lock, but observation may sometimes require drilling through the top, sides or rear of the safe. While observing the lock, the locksmith in Palm Beach manipulates the dial to align the lock gates so that the fence falls and the bolt is disengaged.
All but the simplest safes in Palm Beach are designed to protect against drilling attacks through the implementation of hardplate steel (extremely wear resistant) or composite hardplate (a casting of metal such as cobalt-vanadium alloys with embedded tungsten carbide chips designed to shatter the cutting tips of a drill bit) within the safe, protecting the locking mechanism and other critical areas such as the locking bolts. The use of hardplate ensures that conventional drilling is not successful when used against the safe. Drilling through hardplate requires the use of special-purpose diamond or tungsten-carbide drill-bits. Even then, this can be a time-consuming and difficult process with safes equipped with modern composite hardplates.
Some high security safes in Palm Beach use what is called a glass relocker. It is a piece of tempered glass mounted between the safe door and the combination lock. It has wires attached to the edges. These wires lead to randomly located, spring-loaded bolts. If an attempt is made to penetrate the safe, the drill or torch breaks the glass, releasing the bolts. These bolts block the retraction of the main locking bolts. To drill a safe with a glass relocker, side, top, or rear drilling may be necessary. Many modern high-security safes also incorporate thermal relockers in conjunction with glass-based relockers (usually a fusible link as part of the relocker cabling), which also activate when the temperature of a safe exceeds a certain level as a defense against torches and thermal lances.
