What Makes a Door "Smart Lock Ready"?
Not every door is automatically compatible, but most are. Smart locks are designed around the standard American door prep: a 2 1/8-inch bore hole (the large round hole where your deadbolt sits) and a 2 3/8-inch or 2 3/4-inch backset (the distance from the edge of the door to the center of that hole). If your door already has a deadbolt, there's a good chance it's already sized correctly.
Before buying a lock, measure your backset with a tape measure. Open the door and measure from the edge to the center of the existing deadbolt cylinder. Schlage and Kwikset smart locks typically include hardware for both backset sizes in the box, though not all brands do.
Door thickness is the other factor. Standard residential doors are 1 3/8 to 1 3/4 inches thick. Most smart locks fit within that range. Thicker doors โ common in commercial buildings or heavily insulated exterior doors โ may require an extension kit or a different model entirely.
Old Town and CSU-Area Doors: Where Compatibility Gets Complicated
Fort Collins has a wide range of housing stock. Homes in the Old Town neighborhood โ many built between 1900 and 1940 โ sometimes have non-standard door prep. Older wood doors can be thicker, have smaller original bore holes, or feature antique mortise lock hardware that doesn't convert directly to modern deadbolt-style smart locks without modification.
If you're in the CSU and University area, you're likely dealing with a rental built in the 1970s or 1980s. Those doors generally have standard prep and accept a smart lock without additional work โ though renters must get landlord approval first.
Homes in the Harmony Corridor and newer subdivisions in Timnath or Windsor are typically smart-lock-ready out of the box. Builders in those developments have been installing pre-bored, standard-dimension doors for decades. Brands like August and Yale retrofit over your existing deadbolt cylinder, making them especially easy fits in newer construction.
Colorado's Climate Makes Installation Alignment Critical
Colorado's temperature swings โ from below zero in January to 95ยฐF in July โ cause wood door frames to expand and contract significantly. If a smart lock is installed when the door fits perfectly in summer, the bolt may bind or fail to retract cleanly when the frame contracts in winter.
Local locksmiths refer to this as a "cold-bind" โ the deadbolt won't throw or retract because the door has shifted in the frame. It's more common in Fort Collins than in milder climates, particularly with the heavy insulated exterior doors popular in high-altitude construction.
Professional installation accounts for seasonal movement by positioning the strike plate and setting bolt throw length with winter clearance in mind. Overlooking this means a $200 smart lock that stops working reliably by February.
Renters: You Need Permission First
Colorado law doesn't specifically ban renters from installing smart locks, but your lease almost certainly restricts alterations to door hardware. Most Fort Collins rental agreements require written landlord consent before modifying locks. Violating this clause can result in loss of your security deposit or early lease termination.
Some landlords in the CSU area approve smart lock installations, especially if you agree to restore the original hardware when you move out. The August Wi-Fi Smart Lock is popular with renters because it installs over the existing interior thumb-turn without requiring changes to the keyed cylinder โ your landlord keeps their key while you get a keypad.
Get any approval in writing. A text message confirming permission is better than a verbal agreement if there's a dispute at move-out.
What Smart Lock Installation Costs in Fort Collins
Labor for professional smart lock installation in Fort Collins typically runs $150โ$250, covering assessment, installation, alignment, and basic setup. The lock itself costs $100โ$350 depending on features โ Kwikset Halo sits at the lower end, Yale Assure and Schlage Encode in the middle range, and Ultraloq or high-security models toward the top.
Enlarging a bore hole or relocating a strike plate adds $50โ$100. Old Town homes with non-standard hardware may require additional prep work that increases total cost.

Most Fort Collins doors are smart lock compatible, but compatibility isn't guaranteed. Check your bore hole size, backset, and door thickness before buying. If you're in Old Town, get a hardware assessment first โ older homes often have non-standard prep that requires extra work. Colorado's temperature swings mean installation alignment matters more here than in most places. And if you rent, get landlord approval in writing before touching the hardware.
