Spynex anti-theft
We're a Spynex dealer, so you get the unit and a certified install from the same guy, at your house. Your factory buttons become a pincode, the module hides on the CAN bus, and the car doesn't run without your code.

Spynex.
Sold and installed here.
We're a Spynex dealer, so the unit and the install come from the same guy, in one trip. Spynex has been building immobilizers since 2008 and covers roughly 99% of vehicles, with custom firmware when a car needs it.
Spynex dealer · La HabraYour buttons become the key
Spynex turns your car's own factory buttons into a pincode. No code, and the engine stays immobilized.
Hidden on the CAN bus
A small module gets hidden in the car and reads the CAN bus directly. It's a non-invasive tap into the digital bus, not cut and spliced factory wires.
Run it from your phone
The Spynex app changes your pincode, puts the car in service mode, arms and disarms it, and shows live security status.
Code only
Spynex Pin
Your factory buttons are the only key. Nothing extra on your keychain, nothing to lose.
Code + Bluetooth Tag
Spynex Tag
Adds a Bluetooth Tag as a second way in. It has a motion sensor and goes silent when it sits still, so a relay box outside your house has nothing to grab.
The Spynex app
Your phone runs it.
Your buttons unlock it.
Lose the phone and the pincode still works on the factory buttons. The app is for control, not a crutch.
Service mode
A mechanic can start and move the car without your code.
Arm, disarm, status
Arm it, disarm it, turn it off, and see live security status.
Spynex Tag
Optional Bluetooth Tag that goes silent when it sits still, so relays get nothing.
How they're taking them
A factory alarm won't stop a car that thinks it has a key.
None of this needs a broken window or a tow truck. It needs your car to accept a key, a signal or a message that isn't really yours.
Key programming at the OBD port
Get inside, plug a programmer into the diagnostic port under the dash, pair a blank key. The car sees a valid key and starts.
Relay attacks on keyless cars
One box near your front door picks up your fob. A second box at the car repeats it. The car opens and starts like you're standing next to it.
Going in through the wiring
Some crews skip the cabin and tap the car's network from wiring behind a headlight or bumper, sending the same messages a real key would.
An immobilizer like Spynex or IGLA sits on the car's CAN bus and keeps the engine blocked until your code goes in on the car's own buttons. A programmed key, a relayed fob or a spoofed message still gets them a car that won't drive.
Worried about a flatbed? An immobilizer stops it driving away. Ask about adding a GPS tracker for the rest.IGLA vs Spynex
IGLA or Spynex?
Same goal. Here's the difference.
Both keep the engine blocked until your code goes in. Both hide on the CAN bus. Here's where they split, straight from each brand.

"Had a great experience with 12 Volt Shield Pros! Junior installed Spynex on my vehicle and did a great job. He was quick, knowledgeable, and answered all my questions. He even came to my location, which made everything super convenient. Definitely recommend!"Jonny S. · Google review · 5.0 on Google

Does an immobilizer stop OBD key programming?
A thief can still program a key, but that's all they get. The immobilizer keeps the engine blocked until your code goes in, so a programmed key gets them a car that won't drive.
What if I lose my phone?
With Spynex your pincode still works on the factory buttons without the app or the Tag. If you ever need it reset, we reconfigure it.
Can a mechanic or car wash still move my car?
Yes. Spynex and IGLA both have a service mode, so a mechanic can start and move the car without learning your code.
Can I install Spynex myself?
No. Spynex is installed by certified technicians only, because a bad install can affect the car's safety systems.
Do I need to carry anything extra?
Not with Spynex Pin. Your factory buttons are the only key. Spynex Tag adds an optional Bluetooth Tag you can use instead of the code.
Can I change my code later?
Yes, anytime, right from the Spynex app. No trip back to us.
