Aftermarket remote problems

[boxfix]

I installed an aftermarket remote fob lock/unlocking system on my 2003 Boxster.

It locks fine, but will not unlock.

I followed the instructions in the posts on this site and tapped into the lock and unlock wires under the driver's seat and installed the new unit there.

It works great......locks and unlocks properly when pressing the appropriate buttons.
Walk away and leave it for say 1/2 hours and it will not unlock with the remote. I have to put the key in the door to unlock the car. It unlocks fine and then the alarm will go off in 30 seconds or so. Have to get the key in and turned to turn off the alarm.

Any ideas what is going on? I feel like I am hooked up to the proper unlock wire.

Anyone have this problem?

Thanks.

Unfortunately, I can't give you specifics as to why, other than an intermittent signal loss, or system confusion somewhere. I would troubleshoot the "brain" and see if there is a reset setting or something you may have missed. There could also be some sort of current from the stock system (if still on board) running through it's system checks.

There is a reasonably amount of info out there that an aftermarket system is a total nightmare due to the complexity of the stock alarm/security system. This even goes as far as not installing an aftermarket stereo to a degree.

Where did you get your +12 volts? I had this same issue and discovered that the wire I tapped for power was not constant power.
