are there any more tests that i can perform to make sure the EIS is not faulty and the problem is with the key. anyway i was planning to get the new chrome key, but i dont want to get it and then discover that the EIS is broken. in that case i will have to get one more key rite, coz the 1st new key will be programmed with the old EIS. or can we reprogram the key if we install a new EIS?
