Saflok hh6 troubleshooting
If the Saflok handheld programmer (HH6) is not working or you are experiencing difficulties with your programming software, consult the following troubleshooting guide.

Check SAFLOK HH6 Flash Battery
Check the Saflok handheld programmer battery level and ensure it isn’t low. If it is, charge up the battery using a wall charger or USB cable.
Ensure that both batteries in the programmer have been charged to the total capacity. If you purchased new batteries, they must be fully charged before use.
It is best practice to remove one battery after each use until you get it right and then continue with the second battery so they can both be fully charged at separate times instead of both being discharged simultaneously.
If the Saflok hh6 battery is not charging, try this:
- Remove the battery and put it back in.
- Check if there is any damage to the prongs of your Saflok hh6 programmer manual. Use a clean cloth to wipe off any dirt or dust on these parts of your programmer cable.
- Try using another power source and make sure that it’s connected properly with no loose connections between its wires and electrical outlets (or you can check it with an ammeter).
Check SAFLOK HH6 Programmer Cable
Make sure the Saflok hh6 programmer cable is connected to your PC. The SAFLOK HH6 programmer cable is a USB-A to mini-USB cable that connects the handheld programmer to your computer. The length of the cable is 1.8 meters (5 feet).
Ensure that the operator keypad or programmer cable is firmly connected to the central unit and powered up correctly by checking with another device such as a phone charger or laptop computer if possible because sometimes this connection must be changed depending on what type of device is available for testing purposes;
Refer to the Saflok hh6 handheld programmer manual if you need more troubleshooting steps or additional information on how to operate and program your device
Saflok encoder troubleshooting
If you have difficulties with the Saflok encoder, we have a few troubleshooting tips to help you get back on track.

If your Saflok encoder is not working, check a few things.
- First, ensure that the hotel key card is not damaged or scratched. If it is, that may be causing the problem.
- Check that the cable connecting your Saflok encoder to a computer is secure, with no exposed wires or damage. If there is any visible damage on either end of this cable, you will need to replace it before attempting to use your safe lock again.
- The unit is not communicating with your computer. If this is the case, check if your USB cable is plugged in correctly and connected to both devices (the computer and Saflok pad). Try unplugging both devices, waiting 10 seconds, and then plugging them back in again. If this doesn’t solve it, contact us for further troubleshooting advice.
- Check the power supply. The first thing to check is whether or not the device has power. If there isn’t any light coming on, it could mean that there’s no power running through the system at all.
- Make sure that both ends are clean and dry before continuing with programming. You can use rubbing alcohol or an alcohol-based sanitizing wipe for this task if needed (make sure no residue remains after cleaning).
- The Saflok encoder light is blinking red and green alternately. This means that the system has detected an error with the encoder and needs to be serviced by a technician.
- The Saflok light is on steady instead of blinking. This means that there are no problems with your lock.
- Check for other errors on labels by looking at error codes listed by your printer manufacturer (if applicable). This can give some insight into what may be causing problems with your Saflok encoder so that they can be fixed accordingly!
Saflok mt RFID troubleshooting
Saflok MT RFID is a hotel door lock system that includes an electronic locking mechanism and a proximity card reader. If your Saflok MT RFID locks have problems, you can try troubleshooting with the following steps:
- Is power connected? If not, check all Saflok MT RFID lock batteries and replace them. Then test again.
- Is there proper voltage at both ends of each wire in every circuit? If not, repair/replace wiring as needed before retesting.
- Solid green – The system has power and is ready to use. You may need to press the * button on the keypad or touch off once with your card for the door to unlock. If this does not work, try pressing * again.
- A flashing red light will indicate that your battery is low and should be replaced soon!
- Fast blinking green indicates that a valid card has been swiped but failed authorization due to no way being found through which it could pass.
- If the light doesn’t blink when you enter your code, something may be wrong with your system—perhaps it needs to be reset or programmed again by a professional.
- If neither of these steps works, then contact Saflok customer service immediately so they can help resolve this issue!
- Also, you can check the above Saflok RFID light codes for your reference to solve your problems.
Saflok key troubleshooting
Saflok key troubleshooting is essential for getting your Saflok key system to work correctly.
If your Saflok key is not working that you need to resolve, then there are simple steps that will help make sure that everything gets fixed up right away. Just follow these instructions carefully:
- First off, Please confirm your Saflok key has been programmed.
- If your Saflok key has been programmed, please confirm you are trying to open the right programmed Saflok door lock. Some people may try to open the wrong lock.
- If you confirm both the Saflok key and Saflok door lock are all programmed, please check the Saflok door lock batteries.
- If nothing seems to be working, then try removing any dirt or debris from around where you’re trying to insert your Saflok into its corresponding lock mechanism–this includes dust particles!
Other Common Saflok lock faults

Saflok lock is not working.
If your Saflok lock is not working or has trouble opening it, a few common issues can be resolved with the following troubleshooting steps.
- Make sure that the battery is charged and inserted correctly.
- Reset the lock by pressing both buttons at once for five seconds (you will hear two short beeps). This will reset all settings on the lock to their original factory settings so that you can start over from scratch if necessary!
- Try using different keys/cards until your issue has been resolved; this may help determine whether something is wrong with one particular card/key rather than your entire system altogether, which would require more extensive repairs down the road.
- This may be due to an error in the programming of your keycard.
Saflok locks are not accepting keycards (when they should).
If your Saflok lock fails to respond, it is probably because of one of the following reasons:
- The batteries need to be replaced.
- The card reader may have become clogged with dirt and lint over time. To fix this, simply clean out the slot using a small brush or blow it gently until all debris is removed.
- The keypad could be malfunctioning due to water damage or excessive moisture exposure (it’s important not to leave your keypad near running water).
- Try to reset the Saflok lock. This should reboot your lock and get everything working again.
- If this doesn’t work and you’re still having trouble unlocking your Saflok, try using a different keycard with the device; if one keycard doesn’t open it, then there’s probably something wrong with that particular card and not necessarily anything to do with the lock itself.
The Saflok lock isn’t turning/responding.
If your device isn’t responding when turning, there may be an issue with its battery and the motor. A common problem associated with batteries in electronics like these is overcharging; ensure that you’re using the correct charger for your item – if possible – and remove it from charge once full (this will vary depending on the device).
Your Saflok lock is not opening. This can happen if the batteries are dead or the door latch is damaged. If this is the case, you’ll need to replace it and fix your problem. or you are using an invalid key.
If your Saflok lock does not beep, there could be a problem with the speaker or its wiring.
If your Saflok lock does not lock and unlocks instead, someone else may have opened it using their keycard and code before you tried to use yours.
If your keycard isn’t working correctly, make sure that it has been registered correctly with the lock.
How do I reset the Saflok MT RFID?

To reset your Saflok MT RFID, follow these steps:
- Gather the following materials: a flat-head screwdriver and a small piece of paper.
- Remove the battery from its compartment using a flat-head screwdriver or similar tool. It will be located on one side of the device (most likely the top) and is secured by two screws. The battery can be removed by gently prying it up with your fingers; however, if you have difficulty removing it, try using a small piece of paper between your fingertips and the end cap as leverage.
- Once this cap has been removed, there will be two screws securing an internal cover plate which should also be removed with either fingers or another small flathead screwdriver used to pry off this plate while applying slight pressure towards yourself so that nothing falls out into your hand(s).
- As long as care is taken during these steps, nobody should get hurt or lose anything valuable! You’ll now see two boards labeled R1 and R2 – these are where we’re going next because they contain our microchips which need replacing when they become faulty due to normal wear-and-tear over time (usually less than ten years but up to 20 depending on usage).
