Just tried on my project car. Turned first key on. Chirp after 3 seconds but left in for 6. Changed to second key. After 3 seconds got chirp then nada. No more chirps no flashie. Both originals still work but not new one. Repeated test four times. Since never get flashie I doubt that the new key makes any difference. Just going to have to wait for 2nd order of 7930s gets here (earlier tried 7931 and 7935 but neither worked. 7930s is last chance).
