Short answer: A lock is only as strong as the door, the frame, and the screws holding everything together. Before you spend money on a fancy deadbolt, here is how to judge whether your current setup would genuinely resist a break-in and what to reinforce first.

When a door gets kicked in, the lock almost never fails; the frame splits where the strike plate is mounted. The reason is that many strike plates ship with short three-quarter-inch screws that bite only into the thin door jamb, not the framing behind it. Swapping those for a heavy-gauge or box strike plate secured with three-inch screws that reach into the wall stud dramatically increases how much force the doorway can take, and it is one of the cheapest security upgrades you can make. It also helps to look at the door itself: a hollow-core or thin exterior door undermines even a good deadbolt, while a solid-core wood or metal-clad door gives the lock something substantial to anchor into.
Quality deadbolts carry an ANSI/BHMA grade, and Grade 1 is the most rugged residential rating, followed by Grade 2 and then Grade 3, so knowing your lock's grade tells you roughly how much abuse it is built to survive. Beyond the grade, you want a bolt with a full one-inch throw, meaning it extends at least an inch into the frame when fully locked, since a short or partially thrown bolt is far easier to defeat. Better cylinders also add anti-drill pins and bump or pick resistance. If you have glass sidelights or a window within arm's reach of the lock, a double-cylinder deadbolt that needs a key on both sides removes the easy reach-through unlock, but weigh that against fire-escape safety and check that it is permitted where you live, since a keyed interior can slow an exit during an emergency.
A single strong lock is a good start, but layered security is what actually discourages someone from trying. Sliding patio doors are a common soft spot, so add a bar or a pin in the upper track so the door cannot be lifted out or slid open even if the latch is compromised. The interior door from an attached garage is another frequently overlooked entry point that deserves the same grade of deadbolt as your front door, because a garage often shields an intruder from view. Good exterior lighting and clear sightlines matter too, since most opportunistic break-ins prefer darkness and cover. If you use a smart lock, treat its access log and alerts as a helpful layer rather than the whole strategy, and keep the mechanical hardware behind it just as solid.
