Long exposure with no remote?

I just got my K5 a few days ago. The Remote WP that I also ordered came in today but it doesn't seem to work. I set the drive mode to Remote and the blinking light comes on but when I hit the button on the remote nothing happens and there's nothing visible (to my naked eye) on the front beam (LED?) on the remote.

Anyway, Pentax is going to give me a full refund so that's not my problem. Now my problem is that I'm leaving in the morning for a week of shooting night shots up in Big Sur and I don't know if there's a way to take long (30 minutes+) exposures without a remote.

Can somebody tell me if there's a way to do this without holding the button the whole time?

I'm a little surprised with all the bells & whistles it's got we can't just program how long we want the exposure to be.

Baffling, really.

With my K7 I just set the drive mode to 2 sec delay, press the shutter and it will stop when I hit the shutter again (I dont like that last bit as it can introduce shake) so maybe its a menu option, my K7 isn't here so I can't check for you. .
However if the long exposure is 30 secs or less you can just use dial in the length and it will finish automatically.

watch an episode of MacGuyver on youtube to put you in the spirit.
I am thinking just grab a pair of airplane-type cheapie headphones and use scissors to clip the wires just upstream from the plug. hot wire a switch for long exposures by twisting the wires closed to complete the circuit, pull apart to break the circuit. i havent done this, but wouldnt it work for simple bulb exposures??

also, another poster mentioned the camera shake from touching the button. You can still overcome this when triggering with your finger by holding a piece of card(black is best to prevent any reflection) in front of the lens, pressing the shutter to open it and then sliding the card away to begin exposing. reverse the process to close the shutter without any camera shake. This is the way the old school photogs did it before the shutter was invented.

Tonto, that's a workable solution. How do I program the shutter to stay open after the shutter button is released?

FWIW, this is expected behaviour. The IR beam from the remote isn't visible to the human eye, there is no visual indication it has worked. Same goes for TV remotes, or anything else using IR emitting diodes.

I'd suggest you double check your camera settings before forsaking the remote as dead. In a pinch though, some (many?) TV remotes will also trigger your camera. You'll have to play around to see what buttons or settings (e.g. for universal remotes) will work for you.

Are you sure there are batteries in the remote?

Just a query. I am assuming that this works with the k7 and k5 even though they are not listed on the Pentax list.

get a cheap cable release at nearest camera store. Get the canon version with the headphone jack end. 1/8" Bring your K5 to test it. But double check that you are using correct settings with ir remote. Makes sure the battery is installed correctly. 30 minute exposures? Thats pretty long! I guess there isn't much light pollution out there. Big Sur? Wow what a beautiful place! Grab some nice shots. I wish I lived around Cali.

Having re-read your post in regards to 30min exposures it would be pretty hard to keep the shutter pressed down that long with an IR beam.
What you want is something like this:

You don't need to keep it pressed. You can set the IR remote settings to allow one press to open the shutter, a second press to close it.

Indeed. p116 of the K-5 manual mentions this.

The setting is under Menu > C > 3 > 19: Remote control in Bulb.
Choose 'Mode 1'.
