My 2012 Outlander was hit in the rear. Now I get Keyless entry service required. The two buzzer (8637A121) and buzzer one next to it. My 2 front doors little buttons on the handles don't work. I replaced the other 8637A136. My question is do I need too change 8637A121 also. Only the plugs were damaged. I dont know if it needs to be programmed
