Automotive Electronics Lab-Shop · Houston & Katy, TX
Javoosi is a bench-and-mobile electronics shop for the jobs regular mechanics send away: computer diagnostics, key & anti-theft service, and dealer-level module programming — at your location around Houston, or by mail from anywhere in the country.
What we do
Every service below is performed with dealer-level and factory-licensed equipment. Pick your vehicle on the pricing page to see exactly what applies to your year and model.
Full-system scans with a written finding, CAN-bus and network faults, and the intermittent problems other shops give back unsolved.
Typical job — "Multiple systems offline" traced to one failed module, not five guessed parts.
Spare keys, replacement fobs, and all-keys-lost recovery — including Mercedes, BMW & Mini, Audi, Land Rover, and Porsche specialty work.
Typical job — Every key lost on a 2011 E-Class, recovered at your driveway.
Factory software updates, replacement computers installed and married to the car, and used modules renewed instead of dealer-priced new ones.
Typical job — Used BMW engine computer matched to the car. No dealer visit.
Gearbox computers cloned, virginized, and adapted so a used replacement drops right in.
Typical job — 7G-Tronic computer renewed and adapted, same day on the bench.
The famous failures, fixed: BMW footwell (FRM) modules, Mercedes and Audi steering locks, instrument clusters, airbag modules after a deployment, feature coding and retrofits.
Typical job — FRM dead after a jump start: repaired with your coding preserved, $150.
DPF forced regens, DEF/AdBlue faults, injector coding — light trucks through Class 8. Dealer-level truck diagnostics at your yard.
Typical job — 5-MPH derate diagnosed and cleared before the load is late.
Battery registration, parking-brake service mode, steering angle resets, ABS bleeds, TPMS, air-suspension calibration, hidden feature coding.
Typical job — European battery replaced elsewhere? Registered correctly in 20 minutes.
ABS units, body control modules (BCM), and engine computers (ECM) repaired at the component level — water damage, burned drivers, cold solder joints — so you keep your original module instead of buying new.
Typical job — ABS module with a dead pump driver rebuilt. No replacement, no coding: it's still your module.
Our engineering side: custom electronics designed and built in-house — AC control, fuel pump control, push-button start, wiper and lighting logic, delay timers, and complete custom digital instrument clusters.
Typical job — Intermittent fuel-pump control on a discontinued model, fixed for good with a purpose-built module.
Old analog gauges replaced with a custom digital cluster designed and built in-house — speed, RPM, fuel, temperature, oil pressure and voltage on one clear screen, wired to the truck's original sensors.
Featured build — 1995 Chevy C1500: factory analog cluster converted to a full digital display.
Worn-out or failed climate controls replaced with a touch-screen AC panel designed and built in-house — temperature, fan speed, mode and A/C on/off, made to fit the original dash and connect to the vehicle's existing system.
Available for — Nissan · Ford · Chevy. Other makes on request.
When no scan tool on the market can see the fault, we design and build one that can — readers, testers, and data loggers made in-house so problems are found fast instead of guessed at.
Typical job — An intermittent no-start caught with a custom logger that watched the car for a week. See our tools →
Diagnostic tools — designed & built here
Store-bought scanners only show what the manufacturer lets them show. For the faults they miss, we design and build our own diagnostic hardware and software — from the circuit board to the screen — so we can see exactly what the car is doing. Shops and fleets can order these tools too.
Test an electronic throttle body on the bench, out of the car — drive the motor through its full range and watch both position sensors to prove whether the throttle body is good or bad before it goes in.
Example — Idle and reduced-power complaints confirmed or ruled out at the throttle body in minutes, no guessing.
Small recorders left in the vehicle for hours or days that capture voltage drops, power drains, and the fault that only shows up once a week.
Example — Battery logger with a touch screen that shows exactly when a battery drain starts.
CAN-bus and serial testers, sensor and signal simulators, and harness checkers that point to the broken wire or failed module instead of a guess.
Example — Simulate a missing sensor to prove whether the module or the wiring is at fault.
Have a problem you keep seeing? Tell us what you need to measure — we design the circuit, build the board, write the software, and deliver a working tool.
How it works — Describe the problem → we quote → design & build → tested tool in your hands.

Why a lab-shop
Factory-licensed programming software plus specialist bench tools most dealers don't even own.
Oscilloscopes, sensor simulators, and chip-level reads — we fix the module you have instead of selling you a new one.
Every job is confirmed by VIN or part number before booking. If we can't do it, we say so before you spend anything.
No odometer or mileage services of any kind, ever. Key and immobilizer work requires proof of ownership.
Get started
Texting is the fastest way to reach us. Send your year, make, model, the problem (or the module part number for mail-in work), and whether you're in the Houston / Katy area or shipping. We'll confirm coverage and price before anything is booked.
