Key Features
- Patent-pending linear lock delivers up to 700% more unique key codes than standard safety padlock cylinders direct benefit for facilities scaling beyond 20 authorized employees
- 6-pin cylinder provides higher keying complexity than the 4-pin cylinders common in entry-level safety padlocks
- Anodized aluminum body resists corrosion in wet, chemical, and high-humidity environments
- OSHA 29 CFR 1910
- Available in multiple body colors for color-coded multi-trade LOTO programs; black integrates into existing color-assignment systems
- Aluminum body dents under impact; heavy mechanical environments where locks are frequently struck or dropped are better served by Brady's nylon-body SafeKey or a steel-body alternative such as the Master Lock S32D

Brady SafeKey Aluminum Lockout Padlock — Keyed Different (B07RM5LJHD) Overview
The Brady SafeKey aluminum lockout padlock (B07RM5LJHD) is a single-key lockout padlock built for OSHA 29 CFR 1910.147 control of hazardous energy. When a machine is serviced, the authorized worker isolates the energy source, applies this padlock to the disconnect or isolation point, and attaches a lockout tag. The equipment stays de-energized and cannot be restarted until that worker returns and removes their own lock — the core "one worker, one lock, one key" rule of a lockout/tagout program.
This lock is supplied keyed different: every padlock opens with its own unique key, so no other employee can release it. That is what you want when each person must hold sole control of the energy they isolated. If your program instead needs several locks that share one key — for one worker securing multiple points, or a supervisor master set — choose a keyed-alike option from the lockout padlocks range rather than this keyed-different SKU.
The body is aluminum — lightweight on a belt or lockout pouch and non-conductive, which is why aluminum-body padlocks are commonly specified for electrical isolation where a conductive metal lock near live work is a hazard. For multiple isolation points or several workers locking the same machine, add a lockout hasp so each person applies their own padlock to the group. Stage spare locks, tags, and keys at a wall-mounted lockout station so crews can grab a fresh device before every job. For cord- and valve-fed equipment, combine it with cable lockouts or plug lockouts to cover the full isolation sequence.
What It Is Built For
| Use case | Fit | Buyer guidance |
|---|---|---|
| Electrical disconnect / panel lockout | Strong fit | Non-conductive aluminum body suits electrical isolation; one worker applies their own keyed-different lock per 1910.147. |
| Each worker's personal LOTO lock | Strong fit | Keyed different gives every employee sole control — no one else's key opens it. |
| Multi-point machine isolation | Pair with a hasp | Use a lockout hasp so several keyed-different padlocks secure one isolation point at once. |
| One worker locking many points with one key | Choose keyed-alike instead | This SKU is keyed different; a keyed-alike set is more practical for single-worker multi-lock use. |
| Supervisor / master-keyed program | Not this SKU | Keyed different ships unique keys; a master-keyed system is a separate configuration. |
| Group lockout box program | Workable | Stock keyed-different locks at a lockout station so each crew member draws their own device and key. |
Lockout/tagout devices are part of an OSHA 29 CFR 1910.147 energy-control program. A lock isolates hazardous energy (electrical, hydraulic, pneumatic, mechanical) so equipment cannot be re-energized during service. Each authorized worker applies their own keyed-different lock and a tag; never share or remove another worker's lock. The hardware is only as good as the written procedure, training, and verification of zero energy behind it. Browse lockout/tagout devices.
Pros & Cons
Pros
- Keyed different — each padlock has a unique key, enforcing one-worker-one-lock control under 1910.147
- Aluminum body is lightweight for daily belt or pouch carry
- Non-conductive aluminum suits electrical lockout where a conductive lock is a hazard
- Brady SafeKey platform is a recognized industrial LOTO line
- Color-/label-ready body supports per-worker identification in a lockout program
- Works with standard lockout hasps for multi-point and multi-worker isolation
Cons
- Keyed different is not ideal when one worker must open several locks with a single key
- No master key — supervisors cannot release it without the assigned worker's key (by design, but a workflow constraint)
- Padlock and tag are applied per worker; a tag is not a substitute for the lock
- Title does not state a third-party safety certification — do not assume one
How It Compares
Within the Brady SafeKey aluminum padlock family, the choice is mostly keying and color, not lock mechanics. Match the keying scheme to how your lockout/tagout program assigns control, then use color to identify workers or departments. All are stocked alongside the wider lockout padlocks range.
| Model | Body | Keying | Best for |
|---|---|---|---|
| SafeKey B07RM5LJHD (this lock) | Aluminum | Keyed different | Each worker holds a unique key — strict one-lock-per-person control |
| SafeKey ALU-BLU-38ST-KD (Blue) | Aluminum | Keyed different | Same control with blue color-coding for a worker/department |
| SafeKey ALU-PRP-38ST-KD (Purple) | Aluminum | Keyed different | Same control with purple color-coding for a worker/department |
If you need padlocks that share one key — for a single worker locking several points, or a group set — look at a keyed-alike configuration in the lockout padlocks collection instead. For multi-worker isolation of one point, add a lockout hasp.

Frequently Asked Questions
What does "keyed different" mean on this Brady SafeKey padlock?
Each padlock opens with its own unique key. No other lock in the set shares that key, so only the worker holding it can remove their lock — the core of one-worker-one-lock control under OSHA 1910.147.
Is this aluminum lockout padlock safe for electrical work?
Yes. Aluminum is non-conductive, which is why aluminum-body padlocks are commonly chosen for electrical isolation where a conductive metal lock near live circuits would be a hazard. Use it as part of a full lockout/tagout sequence.
Should I buy keyed different or keyed alike?
Choose keyed different (this SKU) when each worker must hold sole control of their own lock. Choose a keyed-alike set when one worker needs to open several locks with a single key. Compare options in the lockout padlocks collection.
Does this padlock come with a master key?
The title does not indicate a master-keyed system. Keyed different means unique keys with no shared master, so a supervisor cannot release it without the assigned worker's key. If you need a master system, that is a separate configuration.
How does this padlock satisfy OSHA 29 CFR 1910.147?
It is the physical device that holds an energy-isolating point in the off/safe position. The worker isolates the energy, applies this lock plus a tag, and the equipment cannot be re-energized until that same worker removes their own lock and tag.
Do I still need a tag if I use this lock?
Yes. Standard practice is lock plus tag — the padlock physically secures the isolation point and the tag identifies who applied it and why. Add a tag from the lockout tagout tags collection; a tag alone is not a substitute for the lock.
Can several workers lock out the same machine?
Yes — use a lockout hasp. Each worker applies their own keyed-different padlock to the hasp, and the point stays locked until every worker has removed their individual lock.
How many padlocks does this listing include?
Quantity and packaging are shown on the Amazon listing via the Buy on Amazon button. The title describes a keyed-different SafeKey aluminum padlock; confirm pack count there before ordering for a crew.
What size is the shackle?
Exact shackle dimensions are not stated in the product title, so we do not list a figure here. Check the current specifications on the Amazon listing before purchase to confirm clearance for your disconnect or hasp.
Is this padlock certified to a safety standard?
The title does not state a third-party certification, so we do not claim one. The lock is intended for 1910.147 energy-control programs; verify any standard you require directly on the manufacturer or Amazon listing.
What else do I need to set up a lockout program?
Beyond the padlock, most programs stock tags, hasps for multi-point isolation, and a wall-mounted lockout station to hold spare locks and keys. Cable lockouts and plug lockouts cover cords, breakers, and valves.
Why choose aluminum over a steel-bodied lockout padlock?
Aluminum is lighter for all-day carry and non-conductive for electrical work. If your hazard is purely mechanical with no electrical exposure, other body materials in the lockout padlocks range may also suit — match the body to the hazard.

Nice solid aluminum body with an unusual key. The key can only go in one way and I always seem to try the wrong way the first time. As a lockout lock I actually like having to try a second time giving me another chance to confirm I’m ready to remove this lock.

I never write reviews however I feel like I should on this lock since there are not many posted. Right off the bat, I love this lock. However, I almost returned it right when I opened the box. The reason was that the key was so difficult to put into the lock I had to force the key in by pressing the key on my desk and pushing as hard as possible into the lock. I decided to put one tiny drop of 3-in-1 oil into the keyhole and the lock instantly freed up and works amazingly. Hopefully, my lock was just a factory defect that they didn't put any assembly lube in. The only downside to the oil I used is I had to wipe the key off each time I used it for the first 15 times because otherwise, the key would leave greasy marks on stuff. Final criticism and this will probably be the most important fact for most buyers. This lock comes with only one key, I am unaware of any locksmith that carries the blanks for this key to make you a second one. I really wish that would sell a model of this same lock with 2 or 3 keys, even if it's $10 more expensive I would pay it.

I work in manufacturing and L.O.T.O. is a must! +the locking mechanism is smooth as butter. +the new key design is amazing. I no longer have to jiggle and wiggle to try to get the key in the lock. +the color looks awesome! [Purple] - unfortunately the paint is not very tough. So after just a couple of weeks the paint is already chipping away with normal use. I have only had this a couple of weeks and don't expect any issue with durability. On the strength I really can't say anything because I neither need it for anything strenuous nor will I test it for that. I will be buying a blue one soon! This is a definite BUY!!!

Only one key so beware and key color doesn't match the lock pad color. I use it for my gym locker so it does what it's supposed to.

Warning ! Only one key provided
The lock looks and feels sturdy and well made, however only one key was provided, so should it get lost or broken with the lock engaged you will need a hacksaw.
