If your sliding patio door is difficult to move or lock, it could be due to the rollers. Most patio door rollers can be adjusted to account for wear. Sometimes the rollers are so badly worn or collapsed that the aluminium door frame itself is rubbing on the track. Eventually this rubbing can also destroy the track which will add to the expense.

In the picture above you can see 2 old rollers (left) which we removed from a door in Forest of Dean today. They are pictured with a new roller for comparison. The old rollers are completely worn away ( the only bit left is the bearing). No wonder the door didn’t want to open and couldn’t be locked.
What maintenance should you do for your sliding patio door? Keep the track clean and free dirt and grit. Do NOT lubricate the track. Lubricant on the track will attract grit and encourage the rollers to skid and flat spot. You want your rollers to grip the track and rotate correctly around the bearing. It’s the same as you don’t want your car tyres skidding on oil or ice – you want them gripping the road surface and rotating around the bearing.
This style of Garador lock and handle stopped being made around 1984. They can still be found on old metal garage doors. This type of lock barrel are also found on lockers in changing rooms.
In this example below the keys had been missing for months. We were asked to gain entry and fit a new lock. It is often possible to cut a new key for the lock but the original lock was so old and corroded it was worth fitting a new one.
The garage was one giant cobweb – it needed beating down with a stick to be able to enter!
Car remotes can stop working for several reasons. First thing to check is the battery. These can almost always be easily DIY replaced by popping the back off and swapping the battery out. If that doesn’t work then car key repair may be an option.
Some vehicles (particularly BMW/Land Rover and the blue Transit remotes) can have a rechargeable battery soldered to the circuit board. These are not quickly replaced. Like all re-chargeable batteries they have a limited lifespan and will eventually stop charging. We can replace these batteries when the time comes. For the blue Transit remotes it may be better to replace the remote for a newer type where the battery can be swapped out in seconds.
If the remote won’t work on all the buttons it’s probable that one of them is damaged or the solder joint has cracked. The flat Renault key cards are particularly prone to damage because the fit nicely in the back pocket and they get sat on. Replacing faulty or missing buttons can normally be achieved by anybody who can use a soldering iron. Old perished rubber centre buttons can be upgraded with ceramic buttons.

Even if your remote is working – check that your key actually works in the door locks. Sometimes remotes go flat but customers still can’t open the car because the locks have been changed or are faulty. If you don’t have the correct key for the lock you could be locked out if the remote or vehicle battery go flat.
VW Passat remote in for repair. Button had failed, was loose and rattling around in the case.
The battery in this Freelander 2 remote is a rechargeable type that is soldered to the circuit board. It should charge automatically from the vehicle. Like most rechargeable batteries it has a limited lifespan and will eventually fail and stop working. The blue Ford Transit remote batteries and many BMW remote batteries stop charging after a few years too.
It is not beyond anyone competent with a soldering iron to replace the battery themselves. The remote below is one that we repaired for a customer who preferred not to DIY.

Below is a double glazed unit that we replaced recently. That is water sloshing around but it is not a fish tank – it was a customer’s window. Not only is this unsightly but the insulation properties of the glass are severely reduced.
If you need your double glazed doors are windows repairing anywhere near Forest of Dean or Ross on Wye then give us a call for a quote.

The keys to the above steel ISO storage container had been mislaid. We opened both locks without damaging them. This means when the keys are found the locks can continue to be used. If the keys had been lost permanently it can be quicker just to cut the locks off.
If you’ve lost keys to cheap padlocks it may be easy enough for you to cut or twist the locks off yourself. A good padlock like those pictured here will be too strong or located in a position that household tools may not be able to cut them off. In both the padlocks above and the puck lock below the shackle is completely enclosed when fitted correctly. This prevents bolt croppers or a saw being used to easily cut the lock off.

A random selection of locksmith jobs from Forest of Dean this week.
Lost key replaced for Kia Sorento in Coleford. In between being purchased and collected the original key had been lost. It is normally much cheaper to get an existing key/transponder duplicated than cut and programme a new one from scratch.
Cutting a duplicate key for VW Crafter. Actually for this collaboration between VW and Mercedes the key is a Mercedes blank, but the transponder chip inside the key is VW. The advantage of using a computerised cutting machine such as the one above is that the duplicate key isn’t just a shiny copy of a worn key – the key is cut to correct depths.
Broken uPVC door hinge being replaced. A broken door hinge typically occurs when the door is allowed to swing open in the wind. Sometimes if the same hinge cannot be sourced all 3 or 4 hinges on the door will need replacing. The reason why you can’t just replace one hinge is that unless the centreline of the hinges is the same. If off centre there will be twisting/shearing forces in the hinges.
This is the lock for an Audi with keys locked in the boot in Gloucester. The vehicle is deadlocked (putting a tool down the side of the door to pull a handle/lift a button won’t work). In this case the locks don’t even work (even with the key). Somebody had either replaced them incorrectly or the connecting links had come off No option here for the customer apart from wave goodbye to one of their windows.
2 days later we had another example of a client unable to get into their Audi. They couldn’t use the remote (it had lost synch during battery change), the linkages had again come off the lock so the keys couldn’t be used either. Fortunately it was an older vehicle with manual window winders.
This is the remote PCB for a Saab that was not unlocking. The button has clearly disintegrated. We replaced the button for a new ceramic centred button and it now works fine. These black rubber centre buttons often fall to bits or the rubber perishes.
Above is the ASK (amplitude shift keyed) locking signal for the Saab remote. You can see the highs and lows of the signal trace correspond to the decoded binary sequence below. The remote repeats the signal several times for a single button press. The actual binary sequence will change each time the button is pressed. This ‘rolling code’ makes the illicit capture and replay of the signal to open the vehicle more difficult to achieve. There are ways to do it – but why would you unless you’re a criminal?
This lock was fitted to a commercial premises. It is a Chubb 3G110 which is an excellent detainer lock. (Detainers are a bit like levers found in most mortice locks). This lock costs several times more than a normal mortise lock. (Mortise/mortice – both are ok).
The lock was opened to change the detainers so it operated with a different key. It was immediately obvious that somebody in the past had removed all the detainers. In this condition the lock could be opened just with a screwdriver or lolly stick. What would have been presumed to be a very secure lock actually had no more security than a garden gate latch.

New detainers were fitted to the lock and it now secure – as it was designed to be.
On an unrelated subject, we’ve been called to open 3 separate Mercedes cars this week with keys locked in the boot. One of them was at 3am on the M5. Normally we might open one Merc in a whole year. Not sure why Mercedes owners are being more careless than usual at the moment.
Ross Dean Locksmiths remain open for emergency work. This includes persons locked in/out, unable to secure a property, or essential maintenance (e.g. difficulty locking/unlocking doors). Routine maintenance (e.g. misty windows or blown glass) should be postponed if possible until restrictions are eased.
In order to protect our customers masks/PPE will be worn where necessary. Surfaces we touch will be disinfected upon completion.

Customer was unable to unlock a British Standard 5 lever mortise lock. Original keys were present. The keys were turning but the bolt was not being withdrawn. This is an indication that the bolt thrower has broken off the curtain. Normally you can manually withdraw the bolt back into the lock, but not on this occasion. The bolt was jammed solid, and the door securely locked shut.

In this situation the only option was to cut spread the door/frame and cut the bolt off. The bolts in these ERA Fortress are incredibly tough. It takes a long, long time with a large disc cutter. This requires frequent dousing of the bolt with water to prevent heat building up and setting fire to surrounding woodwork.

This Rhino vehicle bollard was either faulty – or more likely had been maliciously damaged. The key would not turn in the lock, and the lock could not be picked. Vehicles were trapped until our locksmith was able to lower the bollard for the client.
This lock was very incredibly tough and I was very impressed by the resistance it put up. If you’re considering fitting a bollard in your driveway, a Rhino bollard is well worth a look.
