Schlage recommends a “premium alkaline battery,” not a lithium (rechargeable or not), and no off-brand or store-brand batteries. Lithium show full charge until the day they don’t and you may be locked out of your house. Alkalines give a bit of warning before fully dead.

Just change the battery

Great honest review!

Dude, THANK YOU! The click of the Humira pen was triggering my PTSD. So, while I wait to get the prefilled syringes, this is a major lifesaver. Thank you!

What about dirt and debris getting in that opening on the third gen?

I haven’t tried it yet but putting the “end” first is extremely commendable. Mucho appreciate.

@joe, thanks so much for sharing this tip; seems to work for me as well.

Worked like a charm - appreciate the work you put in to helping folks in the same situation out.

Thanks for this, I just fixed mine as opposed to replacing it!

Thanks for the video, unfortunately mine is too far gone.

Thanks for the video. I was able to fix mine. Although it was a pain in the butt. Might almost be worth it to buy a new one if it breaks down again. Thanks again

Live in Michigan where when it gets cold I had this problem. Watched videos similar to this and got it to work for a while, then it failed again. What I did solved the problem. I took off the small spring on that little piston and let gravity do its thing. Just saying, if you clean it up. NO oil, maybe graphite, but I didn't put anything on it. just made sure it was very clean. No problems whatsoever. Hang on to the spring in case, but I don't think you'll need it ever. Mines been off for 6 months.

This is the best how to video I've ever seen. Starting with the end. Showing what bits are needed before starting. Highlighting the problem you can get into if you don't take care with the noticing the orientation of everything as you take it apart. AND it fixed my problem. Just perfect. Thank you sir.

Joe - is there a name for that spring? I know, it is a "spring". But, Schlage has nomenclature and p/n for every device ever made. So, in the absence of any ability to get a human interface, I just need to know how to tell them what I need. For the immediate term, this video hack is brilliant, and it worked. THANKS!

You mean inch lbs. 1,500 ft lbs would be fucking insane. They would use that motor in super cars.

Sorry, but No no no! Please do not do this. You are exposing the medication and also probably wasting it. You already get to buy, ready to inject pre-filled syringes. Then why do this? Am I missing something?

Fixed mine! Thank you!!

I just fixed my Schlage keyless deadbolt by buying a more reputable brand and now my lock doesn’t stop working in freezing weather. I will never recommend Schlage products, no customer service and absolute junk!

Unfortunately i fixed it, got all the way to the end of reassembly and didnt have a physical key to mount the lock flush.

The best video I have ever watched. Just perfection and exactness.

i have the 3453-20 do you think it’s worth buying the surge or should i just stay with my 3453

Your video helped me resolve our issue. So glad I didn’t need to replace the entire lock. Thank you!

Sweet and to the point...oh, and it works!!! Ty

Worked perfect saved me 100 bucks

The surge doesn't have much power in first gear

Hi, could I use this method for Wegovy pen? I need smaller dosages due to availability? Is there a cover to plug the syringe so you can store it back in the fridge for later use?

thanks

Was able to fix my Schlage lock with the instructions from your video. Step by step provided the cure for my lock problem. Thank you!

2551 vs 3453 chk👍

Joe I service many of these as I look after 4 bldg near a University 100 units each just slightly stretch your spring

Can we buy a better spring? The key doesn’t even work when this thing goes out 🤔

you saved me $120, thank you!

How come in this video it isn't noticeable yet in others the gen 3 clearly is faster?

Is this strong enough to do tapcons?

I've had my lock for over 7 years, I figured it was time to replace it. This adjustment worked great! Thank you!

Thanks for the video. You saved me the price and hassle of installing a new lock. It was simple to do once I watched this 'how to video'. I owe you a beer! 👍

This video is great. I took the body apart and reset the spring per your vid. Got it all reset, and changed the battery. The lock is brand new ! Thank you for the instruction. It works.

I understand impacts are loud but I’ve never felt the need to wear ear protection… maybe I have a lot of hearing loss I guess

I dont care if any of the impacts are stonger or faster. I only buy the surge. Or oil impulse

Nope. Buying another brand.

At 1:45 of your video when you press the Schlage button you get a fair bit of travel activated by the solenoid. I get next to nothing. My solenoid is not activating.

Thank you!!!

Still the Belt Clip is not really usable for a normal leather Belt. I switched the original Belt clip of the Gen3 for the one tjat you find on the installation driver and the stapler

Great video. Thanks for sharing. Helped me out for sure.

I’m not sure what happened here but I’ve gone through three M12 surges. The first one the collar broke off and I couldn’t find it and so I took it to Home Depot and they just gave me a new one. It would’ve been an easy fix though the second one got stolen and so I had to pick up a third one. I had the second generation impact M 12 and I just picked up the third generation a few months ago, and the surge is absolutely positively nowhere near as powerful as either of those generations. You can find 1 million TH-cam videos about the M 12 surge versus the regular M 12 in every situation the M 12 annihilate the surge. I mean it’s not even close. Unless I had three defective surge M 12 drills, this video is not accurate at all. All I do is construction work, and the M 12 surge is under powered and heavy although it does have its uses I have the M18 surge. And with the small 2.0 battery it is not that much heavier than the M 12 surge with the six amp battery. Honestly the M 12 surge is not that quiet compared to the M 18 surge. The emetine surge is much more ergonomic and lighter weight and better balance than the regular M 18 impact driver, I love the M 18 surge it handles everything. But my go to tool is the third generation M 12 impact. It is insanely powerful and lightweight and I wear headphones all day with noise canceling so the noise does not bother me at all.

What Null said. Here's the problem, no begging, no junk. If there's a sainthood for TH-cam toots you're a shoo-in.

Now how do you open the rest of the injector to recover the second spring?

Excellent video, thank you very much. Fixed it in 30 minutes

The regular one makes 1500 inch pounds.

Thank you! This video was just what I needed!
