Here is a detailed guide on how to put a lock on a door without drilling.

  1. Use a Portable Door Lock

Portable door locks are innovative devices that provide additional security without drilling or permanent installation. These locks typically attach to the door frame or strike plate and can be easily removed and repositioned. To use a portable door lock:

  • Slide the lock into the strike plate or latch mechanism.
  • Adjust the locking mechanism to secure the door.
  • Follow the manufacturer’s instructions for proper installation and operation.
  1. Install a Door Barricade

Door barricades are another effective option for adding security to a door without drilling. These devices consist of a sturdy metal bar or brace that prevents the door from being forced open from the outside. Hiring Locksmiths in Ware and assigning the job to them is the best thing to do. To install a door barricade:

  • Position the barricade at an angle against the door.
  • Extend the bar or brace until it securely wedges against the floor or door frame.
  • Test the barricade to ensure it is firmly in place and prevents the door from opening.
  1. Utilize a Door Security Bar

Door security bars are adjustable devices that fit securely under the doorknob and extend to the floor, providing an additional layer of security against forced entry. To use a door security bar:

  • Extend the bar to the desired length.
  • Place the footpad against the floor on the interior side of the door.
  • Position the yoke under the doorknob and adjust the height as needed.
  • Apply pressure to the bar to secure it in place.
  1. Try a Door Chain or Slide Bolt

Door chains and slide bolts are simple yet effective locking mechanisms that can be installed without drilling. These devices attach to the door frame and provide a secondary locking option to complement existing locks. To install a door chain or slide bolt:

  • Position the chain or bolt on the interior side of the door.
  • Mark the desired placement on the door frame.
  • Use screws or adhesive mounting pads to secure the chain or bolt in place.
  • Test the mechanism to ensure smooth operation and proper alignment.
  1. Consider a Door Jammer

Door jammers are portable devices that wedge securely under the door handle, preventing it from being turned from the outside. While not a traditional lock, door jammers offer a quick and easy way to enhance security without drilling. To use a door jammer:

  • Place the footpad firmly against the floor on the interior side of the door.
  • Extend the arm of the jammer to the height of the door handle.
  • Apply pressure to the jammer to wedge it securely in place.


Thanks to various innovative solutions available on the market, putting a lock on a door without drilling is feasible. Whether you opt for a portable door lock, door barricade, security bar, door chain, slide bolt, or door jammer, these alternatives offer reliable protection without needing permanent installation. If you find it difficult to DIY, hire a locksmith in Harolow and assign the job to them. They will take the headache off you and complete the job professionally.
