Short answer: Your locks live outside in whatever the weather does, and the seasons attack them in opposite ways. Cold jams them from the inside, heat and humidity swell the door around them. A little seasonal attention keeps exterior locks turning smoothly all year and prevents the freeze-morning lockout nobody wants.

In cold, damp weather, moisture inside a keyway or latch can freeze and leave the mechanism stiff or completely stuck. The instinct to fix it fast is where people cause real damage. Do not pour hot or boiling water over the lock, it refreezes quickly, can crack finishes, and drives more moisture inside. Do not force the key, a key turned hard against a frozen cylinder is exactly how keys snap off, turning a five-minute thaw into a locksmith call. Instead, gently warm the key itself, or apply a purpose-made lock de-icer, and let heat do the work. Prevention beats the scramble: treat exterior locks with a dry or silicone-based lubricant before the cold season, keep water from pooling in the keyway, and a small cover or hood over an exposed padlock goes a long way. Gate and shed padlocks are the most common winter casualties, so give them attention first.
Heat and humidity work on the door and frame rather than the lock. Wood doors and frames absorb moisture and swell, which shifts the alignment between the bolt and the strike plate, so a deadbolt that closed easily in spring starts to bind by midsummer. If your lock suddenly resists only in humid months, suspect the door before the cylinder. Direct sun also bakes metal hardware and can dry out whatever lubrication was there, leaving the mechanism gritty. Check that the door is not dragging on the frame, confirm the bolt still lines up with its strike, and refresh lubrication if the action feels dry. Fixing seasonal misalignment early, sometimes just a strike-plate adjustment, keeps you from forcing a swollen door and stressing the lock every single day until fall.
Twice a year, ideally at the shift into cold weather and again in high summer, walk your exterior openings and give each lock a quick pass. Test that every deadbolt throws fully and every key turns without a fight, since a lock that is merely 'a bit stiff' now is the one that fails in the next weather swing. Look at the weatherstripping and door alignment, a door that seals poorly lets moisture reach the lock. Wipe down exterior hardware, clear any grit from the keyway, and re-lubricate with the right product if the action is dry. Do not forget the low-attention locks: gates, sheds, garage side doors, and mailbox locks tend to be the first to freeze or seize because nobody touches them until they fail. Ten minutes twice a year is far cheaper, in time and money, than an emergency visit on the coldest morning of the year.
