A Briggs and Stratton lawn mower engine can become locked up due to a variety of reasons. Common causes of this type of engine lock-up include a lack of oil in the engine, incorrect fuel and spark plug misfiring.
Disconnected, dirty or fouled spark plugs are common causes for engines that won`t start. For small engines, spark plugs typically need to be replaced every season or after 25 hours of use. You should also check to make sure the spark plug gap is set correctly.
The problem may be in the recoil starter itself. A tangled coil of rope or a broken spring may be the problem. In many cases the recoil starter is easily replaced as a single assembly. DO NOT attempt do take the starter apart.
Seized car engine symptoms:

Fumes/smoke: since the engine can`t turn over, fumes, smoke, and even fire can happen – all of which are a sure sign of an engine seizure. Nothing: the most tell-tale sign of a seized engine is when nothing happens. When your car won`t start no matter how hard you try.

An engine can seize due to running on low/no oil, overheating or succumbing to a broken timing belt. These conditions eventually stop your engine in its tracks and a professional technician will be required to restore function.
A dirty carburetor is one of the most common causes for a lawn mower not being able to start after sitting unused for months or years at a time.
