Best Locks for a Fire Exit Door: Panic Bars and Smart Deadbolts
If you are chaining a bike near a fire exit, the lock that matters is the one on the door, not a cable lock. A bike lock has no place on an exit door, and fitting one is a code violation in most places. The door itself needs hardware that opens in a single motion from the inside without a key, tool or code. We compared published manufacturer specifications, certification listings and owner feedback for both commercial panic hardware and keyless smart deadbolts.
Quick answer
For a shared or commercial fire exit, fit real panic hardware: the Global Door Controls TH1100-ED rim panic exit device is the affordable, code-focused choice, and you must use the fire-rated (non-dogging) version on a fire-rated door. For a home shed or garage side door used as a bike store, the Yale Assure Lock 2 (Wi-Fi) gives keyless entry with an interior thumb turn that still opens in one motion.

Read this first
A deadbolt, padlock, chain or bike lock on a required exit door is not legal in a commercial or shared building. Required exits must open in one motion, from the inside, with no key and no special knowledge. Smart deadbolts in this roundup are for a private shed, garage or bike store side door, not for a marked fire exit in a building others rely on. If the door is a designated fire exit, use listed panic or fire exit hardware and have it checked by your local authority.

Global Door Controls TH1100-ED Panic Exit Device
Best for a Real Fire ExitPros
- Single-motion push-bar egress, no key needed
- No batteries or electronics to fail
- Far cheaper than Von Duprin commercial hardware
Cons
- Surface mounting needs accurate drilling and a strike alignment
- Dogging versions must not be used on a fire-rated door
This is the hardware a fire exit door is actually supposed to have. A rim panic device mounts on the inside face of the door and retracts the latch the moment anyone leans on the bar, which is the single-motion egress that exit codes require. Outside trim can be keyed or blanked off so the door stays secure against entry while remaining free to exit.
One detail buyers get wrong: standard panic devices are usually available with mechanical dogging, which holds the latch retracted so the door pushes open freely. Fire-rated doors must use the non-dogging fire exit version, because a fire door has to latch every time it closes. Check the listing for the fire-rated variant before ordering, and confirm the handing and door width.
Detex ECL-230D Exit Control Lock
Best Alarmed Exit DevicePros
- Sounds a loud local alarm the moment the door is used
- Still allows free exit, so it does not block egress
- Battery powered, no wiring run required
Cons
- Costs more than a plain panic bar
- 9V battery needs a scheduled check
An exit control lock is the answer to the real problem behind bike storage near a fire exit: people propping the door open or using it as a shortcut. The Detex ECL-230D lets anyone push out freely, which keeps the door legal, but it sounds a loud local alarm and needs a key to silence it, so casual misuse stops quickly.
It is a surface-mounted unit built for doors signed as emergency exit only. It is not a substitute for a fire exit device on a fire-rated assembly, so check with your building's fire officer about which model suits your door before ordering.
Yale Assure Lock 2 (Wi-Fi, Keyed)
Best for a Home Bike Store DoorPros
- Interior thumb turn retracts the bolt in one motion, no key inside
- Works with Alexa and Google Home on the Wi-Fi version
- Keyed version keeps a physical key backup
Cons
- Bluetooth-only versions need the Yale Connect Wi-Fi Bridge for remote access
- Not acceptable hardware for a required commercial exit
For a private garage, shed or bike store side door, a keyless deadbolt with an interior thumb turn is the sensible choice. Yale's Assure Lock 2 runs on four AA batteries, typically around six to twelve months depending on how often the keypad is used, and the low battery warning arrives in the app well before the lock stops working. Buy the keyed variant if you want a physical key backup, since Yale also sells a key-free version.
The version linked here has Wi-Fi built in, so you can check whether the door was left unlocked and hand out temporary codes without a separate bridge. Cheaper Assure Lock 2 variants are Bluetooth only and need the Yale Connect Wi-Fi Bridge to do the same, which is the single spec most buyers miss when comparing prices.
August Wi-Fi Smart Lock (4th Gen)
Best RetrofitPros
- Mounts over your existing deadbolt, so your keys still work
- Wi-Fi built in, no separate bridge
- Auto-unlock on approach and auto-lock on a timer
Cons
- Uses CR123A lithium cells, not cheap AAs
- Needs a compatible single-cylinder deadbolt
- No keypad in the box
The August Wi-Fi Smart Lock replaces only the interior thumb turn of an existing single-cylinder deadbolt, which makes it the easiest retrofit here and the only pick that keeps your current keys and exterior cylinder. Installation is genuinely a screwdriver job on most standard deadbolts.
Two specs are worth getting right. The 4th generation runs on two CR123A lithium cells rather than the four AA batteries used by the older Smart Lock Pro, so stock the right spares. And there is no keypad included, so if several people need access you will want August's separate Smart Keypad or a lock with a built-in one.
Schlage Encode Plus Smart WiFi Deadbolt
Best PremiumPros
- Apple Home Key tap-to-unlock with iPhone or Apple Watch
- Keypad plus physical key backup
- Heavy Grade 1 residential deadbolt build
Cons
- Most expensive lock here
- No built-in tamper alarm, that is the Schlage Connect BE469ZP
The Encode Plus is Schlage's premium keypad deadbolt, with Wi-Fi built in and Apple Home Key support so an iPhone or Apple Watch unlocks it with a tap. The mechanical body is the same heavy Grade 1 residential deadbolt Schlage is known for, and the electronics carry a three year warranty, the longest in this roundup.
One correction worth flagging, because it is repeated all over the web: the Encode Plus does not have Schlage's built-in tamper alarm. That feature belongs to the Z-Wave Schlage Connect BE469ZP, which sounds a local siren on forced entry. If an alarm on the door is what you want, buy the Connect, or pair any of these locks with a separate door sensor.
What to check before buying a lock for a fire exit door
Start by working out which kind of door you have. If it is a required exit in a shared, rented or commercial building, the only correct answer is listed panic or fire exit hardware, and no deadbolt, padlock, hasp, chain or bike lock may be added to it. If it is a private shed, garage or bike store door on your own property, US residential rules simply require that you can open it from the inside without a key or any special knowledge, which a thumb turn deadbolt satisfies.
Then check the physical fit. Most US residential doors are 1-3/8 to 1-3/4 inches thick with a 2-3/8 or 2-3/4 inch backset, and smart deadbolts list both. Metal doors often need a different strike and sometimes a spacer, so read the compatibility notes rather than assuming. For panic hardware, you need the door width, the handing, whether the door is fire-rated, and whether you want keyed outside trim or no outside access at all.
Finally, plan for power. Battery locks fail closed, not open, so a dead battery does not trap you inside, but it can lock you out. Pick a model with a clear low-battery warning, keep the right spare cells on hand (AA for Yale and Schlage, CR123A for August), and keep a physical key backup if the model offers one.
Mistakes to avoid
The biggest mistake is treating a fire exit as a security problem to be solved with a stronger lock. Anything that needs a key, a code, a tool or two separate actions to open from the inside is not permitted on a required exit and can be a life safety hazard. If theft through that door is the issue, the right fixes are an alarmed exit device like the Detex, a camera covering the door, and better anchoring for the bikes themselves inside the room.
The second mistake is fitting a standard dogging panic bar to a fire-rated door. Fire doors must latch every time they close, so they need the fire exit version without mechanical dogging. Third, do not overlook exposure: many bike store and side doors face the weather, so check the finish and any IP rating, and keep keypads under a small canopy where you can. And if several people need access, a keypad or a mechanical push bar beats a smartphone-only lock every time.
FAQs
Can I use a bike lock on a fire exit door?
No. A bike lock, chain or padlock on a required exit door blocks escape and is a code violation in commercial and shared buildings. Lock the bikes to an anchor inside the room and leave the door free to open.
Can I use any smart lock on a fire exit door?
No. On a required commercial exit you need listed panic or fire exit hardware, not a deadbolt. Smart deadbolts are fine on a private shed, garage or bike store side door as long as the inside opens with a thumb turn and no key.
What is a panic bar?
A panic bar, or exit device, has a horizontal bar across the inside of the door that retracts the latch as soon as it is pushed. That single motion is exactly what egress codes require, which is why it is standard on commercial fire exits.
What is the difference between panic hardware and fire exit hardware?
They look similar, but fire exit hardware has no mechanical dogging, so the door latches every time it closes. Standard panic hardware often can be dogged open, which is not allowed on a fire-rated door.
Do smart locks work on metal doors?
Often yes, but check the specification. Metal doors can need a different strike, a spacer or a specific backset, and a metal door can also cut Wi-Fi and Bluetooth range, so test the signal before you finish the install.
What batteries do these locks use?
The Yale Assure Lock 2 and Schlage Encode Plus use four AA cells. The August Wi-Fi Smart Lock 4th generation uses two CR123A lithium cells, not AAs. The Detex ECL-230D runs on a single 9V battery.
How often do smart lock batteries need replacing?
Roughly every six to twelve months in normal home use, sooner if the lock is on Wi-Fi and used many times a day. Use fresh alkaline cells and act on the low-battery alert rather than waiting for the lock to stop.
Which smart lock here has a built-in alarm?
None of them. The Schlage model with a built-in tamper siren is the Z-Wave Connect BE469ZP, not the Encode Plus. For an alarm on an exit door, use an exit control lock such as the Detex ECL-230D or add a separate door sensor.
What is the best budget option?
A basic rim panic exit device such as the Global Door Controls TH1100-ED. It is mechanical, has no batteries or electronics to fail, and is far cheaper than name-brand commercial hardware.
Do fire exit locks need to be certified?
Yes. Panic and fire exit hardware in the US is normally listed to UL 305 and tested to ANSI/BHMA A156.3, and fire door assemblies are covered by UL 10C. Check the listing on the product and confirm requirements with your local building department.
Can I install this myself?
A retrofit or replacement deadbolt on a private door is a straightforward DIY job. Panic hardware on a shared or commercial fire exit should be fitted by a professional, because a wrong install can void the fire rating and fail inspection.
Our verdict
If the door is a genuine fire exit, buy exit hardware, not a lock: the Global Door Controls TH1100-ED for basic single-motion egress, or the Detex ECL-230D if the real problem is people propping the door open. If it is a private shed, garage or bike store side door, the Yale Assure Lock 2 (Wi-Fi) is the best keyless choice, with the August Wi-Fi Smart Lock as the easiest retrofit over a deadbolt you already have. Whatever you fit, the bikes should be locked to an anchor inside the room, never to the door.
