## Description

You don’t need to compromise your brand expectations to get what you’re looking for. MUL-T-LOCK offers a low cost solution which is specifically designed to provide standard security while utilizing MUL-T-LOCK’s technology and manufacturing expertise. The solution, Junior by MUL-T-LOCK, offers a comparably-priced, cost-effective product that is superior in design and quality to imitation brands and is supported by a wide dealer network (more than 3000 locations across the country). MUL-T-LOCK encourages consumers to choose a high security platform but understands that there are times when some may choose to forgo with a MT5 or Classic in favor of a more budget friendly solution. MUL-T-LOCK introduced Junior as a way to serve those customers as well because as the name implies, the Junior product offers a scaled down version of MUL-T-LOCK technology at a lesser cost. The decision to reduce product research and development, design and inventory costs by offering a simplified model in multiple finishes and designs is what has allowed MUL-T-LOCK to offer Junior at such a competitive price.

Review: Muy bien pero me llegaron 2 llaves - El producto es excelente. La construcción es robusta y la llave es de los más seguro que hay. Pero me llegaron 2 llaves en vez de 3.
Review: Fits right into the mounting hole of the old lock - I was reading about "lock bumping" in the news. so I bought a set of bump keys on Fleabay (very cheap) just to try it out on my existing front door lock, to see if this is really possible. Also watched a YouTube video as tutorial. So when the keys arrived I tried it out and indeed - without any previous bump training, I had my own front-door lock open in 10 minutes. If I can do that in 10 minutes, a well-trained burglar does that in 10 seconds. So I immediately decided to replace the old lock with a bump-free lock. This Mul-T-Lock is doing the job. it is easy to install (fits the door-hole of the old lock like T), is sturdy and not too expensive. The only thing I do not like is that you get only 3 keys. It comes with a card-code which allows you to order more keys ($15 each, not cheap) at particular locksmiths but my problem is that you then give that locksmith your keycode AND your address. Seems risky to trust someone with that. The way I am going to solve that is to have an acquaintance order the keys for me, who lives at a completely different address (city even). I recommend you do the same if you order this product.

## Questions & Answers

**Q: Why is this (junior cronus) so much cheaper than the interactive+ cronus?**
A: Junior is one step below “high security”. It doesn’t provide drill resistance nor does it really prevent unauthorized key duplication. 
If you’re going for budget - Junior is better than any standard deadbolt. If you want good security I recommend to go one step up to Cronus Interactive+
Mul-T-Lock Interactive+ Cronus High Security Grade 2 Single Cylinder Dead-Bolt w/Thumb Turn 2-3/8 or 2-3/4 Adjustable Backset for Commercial And Residential Metal Or Wood Doors (Stainless Steel) https://www.amazon.com/dp/B07D7HSZDL/ref=cm_sw_r_cp_api_9elVBb3AHBHTR

**Q: Do you have this in a double cylinder version? Keyed on both sides**
A: This is one step up - the INTERACTIVE+ version:
MUL-T-LOCK Double Cylinder Cronus DEADBOLT Interactive+ (Stainless Steel) https://www.amazon.com/dp/B07HFKFFY2/ref=cm_sw_r_cp_api_glt_fabc_Y8ZX0GFQ2MABN7K51SK1

**Q: Where can i find a locksmith familiar with mul-t-lock in the greater wilmington nc area?  no luck with corporate in brooklyn.**
A: It’s a pretty simple lock to install you might have to drill a deeper opening in your door. 
As I’ve installed this lock myself with a cordless drill and wood drill bit...

**Q: Is the junior cronus really bump proof and pick proof? and is the key control really not secure? i ask because i have a very clever nut stalker**
A: I am not sure how 'bump proof' this lock is, but the key is unique (like the old Lexus car keys that are smooth on the outside and ridges cut on the inside).  Blank keys are not sold at Home Depot, so you would need to go to a specialized locksmith to buy a compatible blank to test if it is bump proof.
