AFTERMARKET WINDOW FILM CAN BLOCK ELECTRONIC DEVICE SIGNALS
TECHNICAL SERVICE BULLETIN

SERVICE INFORMATION
Many aftermarket high-performance metallic and ceramic automotive window films can actually block signals associated with common electronic devices such as cell phones, a GPS antenna for a navigation system, or keyless remotes. They can also create audio reception issues and even interfere with a tire pressure monitoring system.
If you're working on an Acura vehicle for a keyless remote or a TPMS problem-and you suspect that window film is the culprit-here's a tip: Try lowering the windows all the way down. If the problem goes away, the window film is blocking the signal.
