What if I lost all my keys?
Contact us.
Will my old key still work after this?
Depends on the current condition of your key.
How do I find my module part number?
It's printed on the label on the module housing. Look for a number starting with 955 637 945.
How long does it take?
3-4 business days from the day your parts arrive, plus return shipping time.
Do you offer a warranty?
6-months warranty
My Cayenne is a 2003–2007. Can you help?

What You're Getting
Professionally manufactured aftermarket control module, enhanced and tested for optimal performance. These units are carefully reworked to meet or exceed OEM specifications, providing reliable functionality at a fraction of dealer prices.

Ship us your faulty module. We extract your original data (VIN, mileage, key codes, calibrations) and transfer it to the new unit, making it identical to your original. Your old module is recycled for parts. You receive a fully programmed, plug-and-play replacement ready to install.

Who We Are
ECU Maverick isn't just another ECU repair shop, we're electronics nerds who happen to love cars. We've been reverse-engineering, bench-testing, and fixing control modules that other shops call "unfixable." While most places only reprogram or swap ICs hoping to solve the problem, we go deeper: component-level repair. That means we can actually diagnose and replace individual circuits on your module's board, not just clone data and hope for the best.
We're based in Fort Myers, Florida, and we work with repair shops, dealerships, and vehicle owners across the country. Our specialty? European brands like BMW, Mercedes, Maserati, Ferrari, Aston Martin, Audi, Porsche, and Land Rover — but we also handle domestic vehicles, heavy equipment, and marine electronics. If it has a control module, we've probably fixed it.
What Makes Us Different
Speed. Most jobs ship back within 2-3 business days. Need it faster? Same-day rush service available.
Plug-and-Play. Every module we repair or program is ready to install — no dealer visit, no extra coding. Just plug it in and drive.
Real People. Text us right now and you'll get a reply from an actual human in minutes. No chatbots, no ticket systems, no "please hold."
Honest Expertise. We've invested years into research and reverse engineering. We don't promise miracles — but when others can't solve it, we often can.
Our Mission
Keep you out of the dealership. Save you time and money. Get your vehicle back on the road — fast, reliable, and backed by our 6+ month warranty. Whether you're a professional shop or a vehicle owner, we treat every job like it's our own car on the line.
