If your DS won't hold games anymore, probably something is wrong with the locking mechanism. If you have no problem, open up the DS (at your OWN RISK) and look into the locking part. Let me repeat, AT YOUR OWN RISK. Only as last resort and your system may get ruined. Best of luck!!!
If your car has an aftermarket alarm then Honda Guy is right. If your car is equipped only with the Honda factory security system then it is very likely due to flexing in the remote case. This usually occurs at night when the Temperature changes which then triggers the panic mode to engage. It can be corrected by replacing the remote or by installing rubber spacers in the remote to reduce the chance of false alarms.
