## 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.
