Schlage Lock Battery Issue

Just an FYI guys…I replaced the battery today in one of my locks and plugged the battery back in and noticed the keypad was dead. Further investigation reveled the wire going to the negative terminal was loose. So if this happens to you just grab the old iron and put a little solder on it.

My Battery meter just turned yellow, I’ll prepare to replace it when it turns red, just wondering if there was a preferred procedure to change the battery. Or any reinitialization or syncing I have to do after the fact.

Actually, the Schlage locks have different set of batteries. One for the keypad and one for the Z-Wave module. The one reported in Vera is for the Z-Wave module in the Schlage lock.

MCV’s response confuses me a bit. I have the Schlage lever lock, and I’m only aware of a single set of 4-AAA batteries that are accessible under the inside plate. Is there another battery someplace else? My battery has started to show slighly less than 100% in Vera for my lock, but I assumed I only had to worry about that one set of batteries.

My Deadbolt has 3 AAA and a 9V. I assume the AAAs are for the zwave radio and the 9V is for the lock mechanism.

So should I replace both sets?
And is there a proper way to do it?

Correct, AAA=Z-Wave and 9Volt=Keypad

I tried using rechargeable AAA’s and although it worked, it showed the battery was almost dead. I guess rechargeables don’t have quite the voltage that disposable’s do, but in many cases there is more Amp hours in the rechargeables

I’m guessing this is all about the deadbolt? My lock has 4 AAAs, for the keypad, and that’s it. :slight_smile:

Slightly offtopic… There are several types of rechargeable batteries:

NiMH - Nickel–metal hydride battery - Wikipedia
LSD NiMH - Nickel–metal hydride battery - Wikipedia
NiCd - Nickel–cadmium battery - Wikipedia
and new NiZn - Nickel–zinc battery - Wikipedia

NiZn has 1.6 volts vs. 1.2 volts of others is one of the advantages of NiZn rechargeable batteries:

Nickel Zinc cells have an open circuit voltage of 1.6 volts. This makes NiZn an excellent replacement for electronic products that were designed to use alkaline primary cells (1.5V). NiCd and NiMH both have open circuit voltages of 1.2v, which may cause some electronic equipment to shut off prior to a complete discharge of the battery because the minimal operating voltage is not provided. Li Ion cells have a much higher open circuit voltage (3.6-3.7v) and are not a suitable replacement for alkaline primary cells; however having resistors in the AA shell with Li-ion cells may approximate the correct cell voltage.

Yes it was the deadbolt that I had to repair the wire on.

Also keep in mind that replacing the AA’s in the deadbolt may shift that microswitch just enough to not engage when unlocked. This is an issue with mine since the battery box/microswitch on my lock isnt milled with the best tolerances…the battery box moves a little when I slide in the battery pack causing issues with my lock status.

Just an FYI

Sounds like you guys have all changed your batteries at least once and it was just a matter of removing the cover and changing the batteries. I’ll assume that there was no reconfiguration or loss of device memory problems.

None - put the new batteries in and your up an running.

I had my 3rd Schlage deadbolt all set up on the desk next to the computer and Vera, and was getting ready to do all the remove/reset/add voodoo to make it work right. I installed the batteries (correctly!), and couldn’t get any feedback from the keyboard. Started to smell ‘hot’ electronics, and went to yank the batteries-one of the AA’s was so hot, I couldn’t touch it! Tried replacing the batteries with know ‘good’ ones-same issue. Obviously, there was a direct shore somewhere within the unit… The retailer sent out a new lock, but the experience was…interesting.
