Our customer in the US contacted us to resolve the issue with their Valet ECU Key intermittently setting off their car alarm and because their buttons had, inevitably, collapsed as is all too common.
After signal testing the key, it transpired the micro-switch behind the hidden 5th (panic button) was sporadically activating causing the erroneous signal. Replacement of the microswitch resolved this issue and we then performed our Glass Key Button Upgrade.
The result, a much better looking, fully working Valet ECU Key,
all turned around within 24 hours for our customer
