Having an issue, I can not get the sentry key system to program the 555c. I have tried all the tricks and will not work. Is there a way to test the 555c?

not really... is it a new unit? remember once it learns one code that's it... it will not be usable again in another vehicle....

how did you program it?

They said it was a new unit. But the box was pretty beat up. I tried following the instructions with the 555c. I used both te keys, but it would go into learn mode but not program the 555c. I did a search and some suggested using both keys but instead of grounding the unit out on the wait to start just cover the second key with tinfoil to fool the sentry key system.
