King's Custom Tires — 4101 Colorado Blvd, Denver, CO 80216
If your interlock has locked you out, the vehicle will not start — so it cannot be driven to a shop. That is what our mobile service is for: we drive to wherever the vehicle is sitting, whether that is your driveway, a work parking lot, or the side of a road. Mobile interlock lockout service is $80 plus the $60 mobile fee — $140 all in within the first 15 miles.
Your monthly state-required recalibration can be mobile too. A mobile recalibration is $95 ($35 recal + $60 mobile) inside 15 miles — useful if you cannot leave work or the vehicle is not drivable. In-shop recalibration stays $35.
We travel up to 75 miles from 4101 Colorado Blvd — Aurora, Lakewood, Westminster, Thornton, Arvada, Commerce City, Boulder, Longmont, Castle Rock, Greeley and most of the Front Range. The first 15 miles are included; past that it is $2 per mile one way, calculated from your address when you book so there is no surprise at the door. Farther out than 75 miles, call (303) 292-3589 for a quote. Every mobile job books a real time slot you pick, mobile calls are prepaid online, and you will need your current odometer reading — the device requires it at service.
King's Custom Tires is an authorized Intoxalock service provider. If Intoxalock is your device provider, everything hands-on happens here: installation, the state-required monthly calibration, lockout service, and removal at the end of your restriction period. You deal directly with the technician who actually works on your vehicle, at one address, in one visit.
Who bills you for what: your device lease and monitoring are billed by Intoxalock directly. We bill only for the work — installation from $190, calibration $35, lockout $80, removal $185. That split also decides where the Colorado DOR assistance goes: up to $400 offsets your Intoxalock lease, not our service fees.
Locked out of an Intoxalock-equipped vehicle, or due for a calibration you can't drive in for? Both can be done mobile, at your location — see the section above for the 75-mile rate card, or call (303) 292-3589.
King's Custom Tires is a certified ignition interlock device installation center serving the Denver metro area. We understand that needing an interlock device can be stressful, which is why we focus on making the process as smooth and discreet as possible. Our trained technicians install devices quickly and correctly, so you can get back to your life.
We work with Colorado's approved interlock device providers and can accommodate most vehicle types, from standard sedans to hybrids, EVs, push-start, and European vehicles. Our installation pricing is competitive and transparent — no hidden fees or surprise charges. Standard installs are $190, and complex vehicles (hybrid, electric, push-start, European) are $285 due to additional wiring requirements. Installations, recalibrations and removals are done here at the shop; lockouts and recalibrations can also be done mobile, at your location.
Our shop is located at 4101 Colorado Blvd, Denver, CO 80216, easily accessible from I-70 and I-25. We serve customers from throughout the Front Range, including Aurora, Lakewood, Westminster, Thornton, and beyond. While you're here, we can also handle any tire needs, brake work, or quick services.
