How we repair it
Strip and inspect
We pinpoint the squib fault and confirm the root cause before any work begins.
Rebuild with OEM parts
Worn or snapped ribbon cables are replaced with OEM items using OEM repair methods — we never solder, as that only leads to short-lifespan fixes.
Test and verify
We test every squib for continuity and function before we send it back, backed by a 12-month workmanship warranty.
