| Yes, with a flat battery the lock can still be opened with the key. If not, then it is installed the wrong way.
No need to get in through the boot or smash a window.

The key system that operates the barrel set in the door handle, and the dead lock system actuated from the inside, are quite unconnected, in a sense.
The dead lock operates a moving lever on the latch mechanism, set into the side of the door, the key simply swings a lever on the key barrel assembly in the handle of the door.
If the central locking failed completely, as long as the button inside the car was in the "Up" position, you could then use the key to lock and unlock the car, in the old way.

No, if the battery, for example, goes flat, and the mechanical buttons
are in the down position, then there is no way to open the door with the key. The mechanical system, ie the buttons inside the car, overides the ability to open the door with the key.
Perhaps the Sonnett set up is different.

| | Without the central locking the key moves the button up and down. The solenoid just needs to duplicate that action. As I said the central locking is just a convenience not an additional deadlock. If it does that I would say that is connected up to the wrong part of the mechanism. Frankly. it is useless if it remains deadlocked if the battery goes flat. The key has to override everything. | |

Maybe I interpret what you write wrongly but there is normally no connection between the key and the button on a 95/96/Sonett lock.

| | I no longer have my 96 but on my Amazon, and my V70, the button goes up and down as I lock and unlock the car with the key. My old Primera was the same and others too. Perhaps I'm wrong in assuming that the Saabs do the same thing? | |

| These locks are the exception to the rule. The cylinder rotates a plate at the same 90 degrees as the key is moved, manouvring in front of or from the mechanism actuator. I guess those 90 degrees make it difficult to connect it mechanically to the rest of the mechanism.

Yep, I've tested it. With the internal buttons down, the external buttons that are operated with the key, do not open the door, irrespective of their position.

To overcome the "flat battery" scenario, I have run a wire from the fuse box, through the car, into the boot. At the fuse box, this wire is connected to the same connection, below the fuse, that feeds the central locking system. If I come back to the car, and the battery is flat, I just have to open the boot, recover the cable, put 12volts between it and earth, and I can then open the doors.(the boot is still manually opened and closed)
I already had a wire running from under the bonnet, to under the back seat for an electric fuel pump. It's currently redundant, so seemed silly not to use it.
No, if the battery, for example, goes flat, and the mechanical buttons
are in the down position, then there is no way to open the door with the key. The mechanical system, ie the buttons inside the car, overides the ability to open the door with the key.

| You could also fit an anderson connector under the front bumper; very useful for jump leads, trickle chargers etc. as well.

| Post script.
Well 15 months down the road, the system still works perefectly, never had to force entry into the car through the boot.
However, one the keyfobs is now on the blink. It will lock the car, but won't unlock it. I'm now using the spare. It's not possible to get new fobs, I asked the company that way back at the beginning. I'd have to buy a new kit, and splice the new ECU, into place, to replace the current one.
Another variation on the theme, I might consider, is only having the central lcoking on the driver's door, leaving the passenger door, permanently locked with the key, (mushroom UP)and simply opening it from the inside, on the very odd occasion when I have a passenger. This would give emergency entry through the passenger door.

| Hello Andy.
Electric garage door fobs can be replaced by universal items; either submitting the frequency details to a fob supplier or some garage non-programmed fobs can record the frequency of the original when they are operated side-by-side.
Hence, I wonder if such an opportunity may exist for a car fob. It is something that I have never looked into, but if garage fobs can adopt the frequency I cannot see why the same principle would not apply to a car fob. At the end of the day, both perform a simple open & close operation. Electric fob frequencies are normally recorded within the unit.
Regards.
Richard. | |

Thanks for that, I'll have a look inside the one that's on the blink, and see if I can see a frequency marked somewhere.

| | A soldering iron might fix your dodgy fob. The little switches under the buttons can come adrift from the circuit board. They have tiny little legs and the solder cracks. Check with a magnifying glass. It may look like a dry joint. Use good thin wire solder and no flux. Good luck. Yes I did this on my Volvo V70 fob. Easy fix. | |
