What to do if…
your bicycle lock is jammed or the key is broken and you cannot free your bike

What to do now

1. Move to a safer pause point. Stand somewhere well lit and visible, such as a station lobby, security desk, staffed building entrance, or busy public area. If you feel threatened or there is immediate danger, call 911.

2. Try only gentle, quick checks for 2–3 minutes.

   • Combination lock: apply light tension to the shackle or chain while turning each dial slowly; check that every dial is fully seated on a number.
   • Keyed lock: make sure the key is fully inserted; use only a gentle wiggle and stop before the key bends.
   • Frozen or dirty lock: warm it with your hand or shelter it from wind if you can do that safely; do not use flame.

3. Create quick proof that the bike is yours.

   • Take photos of the full bicycle, the lock, what it is attached to, and any unique features.
   • Record the exact location and time.
   • Look for the serial or frame number if you can reach it safely; it is often under the bottom bracket, but it may be elsewhere. Do not flip the bike over if that would damage it or draw concern.
   • Pull up anything you already have: a purchase receipt, registration record, Bike Index entry, campus registration, repair invoice, insurance record, or photos of you with the bike.

4. Contact the site owner before arranging a cut.

   • Campus or university property: call campus police, transportation services, facilities, or the posted bike-program contact. Many campus programs require photo ID and proof of ownership or registration before cutting a lock.
   • Transit station or managed bike parking: go to the station agent, customer service desk, parking operator, or security desk; check posted signs for the bike-parking contact.
   • Private property: ask building security, property management, the store manager, or workplace facilities where lock removal is allowed and what proof they need.

5. Use a documented lock-cut option if the lock cannot be opened.

   • If the site has a lock-cut process, follow their ID, proof, location, and presence rules.
   • If the site will not help and local rules allow it, call a mobile locksmith and ask before they come what proof of ownership and site permission they need for a bike lock in public.
   • Ask for the locksmith’s business name, price range, and payment method before agreeing.

6. If you must leave the bike temporarily, reduce misunderstanding.

   • Tell staff, security, or the property owner that the lock failed and that you are arranging help.
   • Consider leaving a short note such as “Owner returning today for lock issue” with only the contact detail you are comfortable sharing.
   • Take a final photo showing the bike, lock, note if used, and location.

7. Choose a safe way home now.

   • Use public transit, rideshare, taxi, a friend, or another safe ride.
   • If it is late, isolated, or you are tired, it is usually safer to go home and return with proper help in daylight than to struggle with the lock in public.
