Product Description
Master Lock 4687DKNL TSA-Accepted Set-Your-Own-Combination Padlock, Luggage LockAmazon.com Product Description
The new TSA-accepted Master Lock padlock 4687DNKL was designed with a security feature that allows TSA airport security agents to open the lock without destroying it. TSA agents are trained to recognize the Travel Sentry Certified logo and should not break the luggage lock. The red indicator pops up when the lock has been opened by TSA. You can reset the lock with your personal combination.
The Transportation Security Administration (TSA) now suggests you lock your checked baggage with TSA-accepted and recognized locks. Travel Sentry™ Certified locks are accepted and recognized by the TSA. Look for the Travel Sentry™ symbol when shopping for TSA-accepted products.
Master Lock has joined together with TSA and Travel Sentry™ to use the special Travel Sentry™ mark on luggage locks that meet the requirements of the TSA. Airline check-in staff are trained to recognize the Travel Sentry™ mark, so they understand that baggage with this special mark is permitted to remain locked. The TSA screeners have access to special tools that allow them to open TSA-accepted locks in the event that your bags must be opened for inspection.
Airport security professionals no longer need to cut your lock or force your bag open and risk damaging it. They simply open your locks, inspect, and relock your bags, sending them quickly and securely on their way.
The red-and-white Travel Sentry™ logo on Master Lock TSA-Accepted locks notifies TSA screeners that they can unlock, inspect, and relock the bag without damaging the lock.
** A red indicator pops up to indicate that TSA has opened the lock. No indicator means that TSA has not opened the lock.

Travel Tips from Master Lock
Whether you’re traveling within the United States or abroad, follow these simple steps to protect you and your belongings:
- When checking your baggage, use a Master Lock TSA-accepted locking device–the one device the airport screeners won’t cut! These locks allow TSA screeners to inspect and relock your baggage without damaging your lock.
- Secure your carry-on bags with a Master Lock TSA-accepted locking closure as an additional safeguard.
- Place your contact information inside and outside your baggage. This provides the fastest way to be reunited with your baggage if it is lost or mishandled.
- Use a TSA-accepted lock on all bags throughout your trip–even in your hotel room and at the bell desk–as an additional theft deterrent. Available locks include: set your own combination, keyed, or locking luggage straps.
- Carry an ATM card, credit cards, or traveler’s checks instead of cash. Keep your traveler’s checks in a money belt under your clothing for extra protection.
- As recommend by the U.S. State Department, register your trip in case of emergency with the free online service: travelregistration.state.gov
- Sign your passport, include emergency contact information, and give copies of it and other important documents to a family member or trusted friend in case of an emergency.

I purchased 4 of these TSA approved locks and am satisfied they will meet my needs. Construction is as expected. These will not keep a thief out, but will keep your luggage closed in normal wear and tear. It will avoid casual theft of opportunity. The alert is a nice feature. I am satisfied with the item as depicted. No 5 star rating since it is clear that a professional thief would only have to obtain a key to open all TSA approved locks.

The lock seems OK and has worked so far. Strangely it’s visible dial is on the end, which is different from others we’ve had and seems awkward.

Ordered 4 of these for an upcoming trip. Amazon put a “4687DNKL” label on all 4 locks, however, the Master Lock packaging clearly shows they are all 4680DNKL locks that do not have the “instant alert” feature.

Used this lock on my last trip overseas. Upon my arrival I found the lock placed inside my luggage and one of the zippers destroyed along with a note from TSA. Apparently not every agent has the key or the knowledge to open this lock. Fortunately nothing was missing however I was left with a broken zipper and money spent for nothing.

After looking for luggage locks that are OK’d by the TSA in several catalogs, I chose to order from Amazon.com. They are great - and the price was lower than others I checked. Delivery was prompt.
