SD Bytes Computer Repair in Grantville, San Diego handles laptop, desktop, Mac, iPhone, iPad, and tablet repair from a storefront at 10433 Friars Rd Suite B, 92120. Owner Shannon Isselhardt founded the business in 2010 after running two prior computer repair operations, bringing more than 20 years of IT field experience to the current sole proprietorship. The service menu covers screen replacement, liquid damage recovery, power jack repair, broken hinge rebuilds, keyboard replacement, virus removal, data recovery, and full hardware upgrades across both Windows and macOS platforms, and the Grantville corridor also supports electronics-adjacent services at Midas on the same Friars Road commercial strip. Data recovery runs a separate diagnostic protocol for clicking or grinding drives, where the shop's intake procedure isolates the failing drive and images it before attempting file extraction. Gaming PC builds round out the hardware side, with custom configurations assembled to spec in the Friars Road workshop. BBB accreditation since 2021 carries an A+ rating, and the shop holds a no-fix-no-pay policy with a 30-day repair guarantee on completed work. Isselhardt and the SD Bytes team volunteer at a local elementary school repairing computers and host Girl Scout troops earning computer badges at the shop's workstations. The Friars Road corridor runs parallel to the I-8 and feeds into the Grantville trolley-adjacent commercial zone, where S3 Coffee Bar anchors the cafe side of the 92120 business cluster. On-site service calls extend repair coverage beyond the storefront for businesses and residences that cannot transport equipment, and all work processes through the same diagnostic-first intake regardless of device type.
