▸ 02 · HOW DISPATCH WORKS

Four steps from your bay to a fix.

Same process for mobile dispatch, J2534 remote sessions, and mail-in bench jobs — the medium changes but the workflow doesn't.

Call or submit a dispatch request

Tell us the OEM, the module, fault codes pulled, and what you've already tried. Five minutes on the phone saves an hour in the bay.

We confirm scope & ETA

Same-day service may be available depending on platform, schedule, parts, and security requirements. We confirm tooling, software, and a window before we roll.

We arrive (or connect) & complete the work

Mobile dispatch: 20-mile travel radius included; $2.50/mi round-trip beyond. Remote sessions begin within minutes once your end is ready. Mail-in modules ship back inside one week typically.

Documented hand-off & net terms

Itemized invoice with pre/post scan reports where applicable. Net-due at completion for new partners; Net-15 or Net-30 available after established history.

▸ 03 · REMOTE & MAIL-IN — US & CANADA

Outside our metro? Still in our service area.

For shops beyond the San Antonio drive radius, two nationwide options. Pick what fits your tooling.

01 / FASTEST

Remote programming — Autel RX or J2534

We connect from our shop to your vehicle through Autel Remote Expert or a J2534 pass-thru device on your end. OEM-authentic and engineering-level software, same internet connection.

▸Most platforms scheduled within hours
▸Typical session 45 min – 3 hours
▸You stay in your bay, we drive the session

02 / DEEPEST

Mail-in bench service

Ship the module. We perform bench-level work that can't go through the OBD port — boot-mode reads, EEPROM extraction, BMW DME ISN retrieval, Mercedes 722.x TCM cloning — and ship it back.

▸Nationwide US + Canada
▸Typical turnaround 24–72 hours bench, <1 week round-trip
▸Wholesale-track pricing

▸ 06 · TRADE-PARTNER FAQ

Most-asked, up top.

The top three trade questions. Full trade-partner FAQ has fifteen more.

What's your service area for mobile dispatch?

San Antonio and the surrounding metro. A 20-mile travel radius from our shop at 4715 N Stahl Park is included (Stone Oak, Helotes, Alamo Heights, Converse, Leon Valley, Selma, Live Oak, Universal City, Cibolo, Schertz). Beyond 20 miles we add a $2.50/mi round-trip charge (Bulverde, Boerne, New Braunfels, Seguin, Floresville, Pleasanton, San Marcos). For shops outside that radius, ask about remote J2534 programming or mail-in bench service — those are nationwide.

What do I need on my end for remote programming?

Two options. (1) Autel Remote Expert — requires a compatible Autel MaxiSys scan tool with Remote Expert enabled. (2) J2534 pass-thru programming — requires a J2534-compliant pass-thru device (Mongoose, DrewTech, Bosch MTC, etc.), a laptop, and a decent internet connection. We handle everything else from our shop.

Are you NASTF VSP credentialed?

Yes. Spot-On's lead technician holds an active NASTF Vehicle Security Professional registration, which is the certification that authorizes lawful access to manufacturer security gateways for key generation, immobilizer service, and Mercedes-Benz TRP requests. This is work a non-credentialed shop cannot legally perform on modern vehicles.
