Uniden alarm playing up

[Scottie]

The earth by the siren came little loose recently, and the siren was making less noise than normal when arming and disarming, aswell as the keyless entry not fully throwing. Fixed the earth and the alarm is now making normal noise and arming and disarming but the keyless entry is not even trying to throw.

anyone have any ideas? the central locking is working fine by key and the button inside.
